Finally signed up for Dabble today. Its a site that allows you to 'bookmark' videos from the web using a handy little 'add to dabble' tool within a your web browser and then tag and organize them on the site. They don't actually host any media, but the idea is very interesting, mostly because in addition to finding your own selections, you can search through those that others have bookmarked. Finding video that you actually want to watch on the web is incredibly difficult, perhaps if they have enough users this will prove to be an interesting step towards a solution. At the very least it seems like a cool way to save the location of stuff you find yourself.
