Joining a small, but growing number of social video apps this week is, a site and an iOS app that allows users to log in to social networks such as Facebook and Twitter, grab videos shared by your friends and followers, and be able to watch them all in one place.  The Shelby video app joins a few other services that launched this year: Showyou,, and Boxee. will play videos from YouTube, Vimeo, and Hulu.  The service was in closed alpha and is now open to everyday users like you and me on the web, iPhone, and iPad. Goes Public, Offers YouTube, Vimeo, and Hulu For Sharing

You often see this type of idea being developed by multiple companies all at once, and whoever wins really will depend on the usual factors: content, ease-of-use, and service.  Just like there are multiple apps that aggregate news like Flipboard, each one vies for success in different ways, trying to become the go-to application.  One thing that the developers of had been working on during its closed alpha stage was to remove duplicate videos, so now one video just lists all the people who have shared it, rather than taking the same video as a new share every single time and clogging up your recommendations.

Here’s’s video demo:

This is a pretty cool idea, since now you don’t have to search for those videos anymore on all of your social media.  Now you can just let the app find them and then you can bookmark them for later viewing, all in one place.  With the apps, this makes the video aggregation portable.  Now you just have to figure out which service is best.  For instance, the Showme service allows users to watch the videos with friends, something Google+ has trumpeted in the public launch of their social network.   No doubt all of these services are looking for content and capabilities no one else has.  Perhaps by next year, one will blow up and be the frontrunner for video sharing.

No doubt these apps will be closely watched by those who make sharing video their business.  These could be remarkable tools for people who create videos and want to share them with a lot of people all at once, as it has a better shot of not getting lost in the shuffle of all the other updates and other videos from social media during the day.
