Redux – It seems everybody’s talking about content curation these days, and many see this as the next level of social interactions online. What it means in simpler terms is that users worldwide share things they’ve discovered on the Web in various venues, in addition to the conventional social networks and blogs. Redux is yet another content curation hub where everyone’s invited to share entertainment finds in the form of photos, music, videos and websites.

Here’s a video I found on Redux that is particularly enchanting. Think of it as your daily chill pill.

Gtrot – The best tips come from family and friends, right? Gtrot uses this underlining axiom to offer a friends-based travel tool. How do they do it? Gtrot invites you to “find Facebook friends who live in your destination, friends who will be there at the same time, and friends who have been there before.” This way, the odds of you having the best trip ever skyrocket to sure success.

Drive & Seek – This interactive, action packed movie is an engaging campaign advertising Mercedes-Benz’s luxurious C Coupe car. Drive & Seek screams 007: the handsome man in the tux dodging bullets and doing car chases, along with beautiful models wearing super tight clothing are apparently the winning formula for getting men all over the world psyched about the C Coupe.

Simply start the movie and play along. That’s all there is to it.

Snail Mail My Email – This unusual free service invites you to write up an email message to whomever you wish, and Snail Mail My Email will hand-write your message on an actual paper letter and send in via post office like in the good old days.

When you think about it, there’s something magical about old-school letters. These can also have greater persuasion power in say, politics, romance or family event contexts than a lifeless email message may hold. But Snail Mail My Email’s goal is different. This project seeks to practice the way people used to interact with each other in the past, using manually written messages. Snail Mail My Email will reverse technology for you, providing your message does not exceed 100 characters. Be sure to provide the recipient’s post mail address, and you can even pick one custom option to be added to your letter (a doodle, a flower petal, spray of perfume or lipstick kiss) and email your message to snailmailmyemail@gmail.com.

The Snail Mail My Email is a temporary, interactive community art project (from July 15 to August 15) made up of 134 volunteers worldwide, all cherishing the “lost art of letter writing.”

Threewords.me – The idea of this unique site is simple. Sign up, send your friends your threewords.me link and see how they describe you (anonymously) using just three words. I guess this is a decent way to get an honest opinion about oneself, and I’m sure many people would love to use it. However, if I were clueless or curious about how I’m perceived by my friends, I would simply ask them face to face instead of using a third party in the form of cold technology. But that’s just me.

Trip Your Face – This brilliant interactive campaign by Hotels.com invites users to experience the “what happens in [city] stays in [city]” for themselves in a whimsical and well-made adventure.

Nexus Contraptions – Instead of going for the conventional advertising campaign to market its Nexus S phone, Google has come up with an engaging way to get your attention. Using its video hosting and sharing platform YouTube, Google’s Nexus Contraptions invites you to play the logic game where you need to get the G ball into the red basket in each level. This emulates building your own Nexus S phone by “bouncing, bubbling, and blasting Google apps into the phone.”

To learn more about Google’s Nexus S phone, start with this fun game, and then explore the device itself.

Memrise – This vocabulary builder is unlike anything I’ve seen online thus far. I visited Memrise thinking I will use it to freshen up the advanced French vocabulary I learned back in college, but I soon found myself learning Mandarin. Memrise is a fast, easy and above all, enjoyable way to learn a new language and to enhance the ones you already speak.

What’s so special about Memrise? The team behind this innovative tool has mastered the science of new knowledge acquisition (especially the kind that’s involved in learning new words) to ensure long-term retention stays above 90%. How? Contributing users fluent enough in a given language give word association tips, and share their way of remembering what words mean. Association, according to science, is the best knowledge and memory retention method. Here’s a solid example of Memrise’s magic, showing how to remember the Mandarin word for Man.

The Memrise magic doesn’t stop there. By using a Farmville-like seed planting and greenhouse growing bait, the system gives you incentives to come back later and practice what you’ve learned. Even the quiz questions are built in a way that helps you remember the new vocab words better. I seriously believe Memrise is a must in every classroom across the country. Well done, Memrise team!

Gojee – This recipe site -named after the funny looking berry from southeastern Europe and Asia- stands out from conventional recipe sites for a few obvious reasons. First, from the first moment you enter Gojee, all you see are large, hi-res, mouth-watering photos. Second, the site shows you (as opposed to merely ‘finds’) curated recipes depending on what you crave and what you currently have at home, while the system eliminates what you hate or can’t eat. The free style recipe search is also available if you must.

Whatever recipe you fall in love with can be shared on Facebook, Twitter or via email, and you can also mark it as a favorite. Who curated and tested these to-drool-for recipes? Meet the savvy cooks and foodie bloggers behind the scenes.

Doggelganger – The Pedigree Adoption Drive in New Zealand came up with a genius project to encourage and increase dog adoptions in the Kiwi country. Together with NEC Technology, Pedigree’s Doggelganger offers a “human to canine pairing software.” What does that mean, exactly? It’s quite simple, really. All you have to do is upload a clear photo of your face (you can also take one with your webcam), make sure the Doggelganger’s face model matches your facial features and hit Begin.

Now the fun begins. The software will match your facial features with those of dogs available for adoption in New Zealand’s SPCA centers. Once a match is found, you’ll see the adorable dog’s face right next to yours. When you think about it, this creates an immediate emotional bond and an instant increase of both the dog’s exposure and the likelihood of finding these dogs a home. Pedigree should do this for the US crowd as well. Most definitely!

What do you think? They really do resemble one another, don’t they?

Prizes.org – Sign up with your Facebook or Twitter account, post a question or a task and offer whatever reward you feel is fair. Prizes is a peer-to-peer Q&A platform where users post inquiry contests others take part in, which means both sides have to gain from this cool service. This site offers an upgraded version of the answers concept, which is why I believe Prizes.org has a serious chance of exceeding Yahoo Answers in terms of honest assistance (as opposed to “lol” and such answers you usually get in such places).

Project Noah – What initially started out as an experimental project by NYU’s Interactive Telecommunications Program later became a mobile app – the interactive and social platform, Project Noah, where ‘scientific spotting’ are entered by users all over the world, and shared with the community. This, as Project Noah’s creators hope, will serve as a “go-to platform for documenting all the world’s organisms and through doing this we hope to develop an effective way to measure Mother Nature’s pulse.” And the best part of Project Noah? It’s designed to work on mobile phones (started with the iPhone). This means you can take a shot of that weird-looking beetle you found during your hike in the woods, and share it on Project Noah, thereby learning more about that organism.

Here’s a screenshot showing what users recently spotted in nature and shared with the Project’s community. Each image you click on takes you to a page where you can see the animal photo’s full size, discover who posted it and where was this taken. This app is particularly beneficial to families with young children, as it’s a wonderful way to experience and learn about the environment and the creatures living within it.
