I don't want to respond negatively, so please don't take it that way. However, I don't really see the big difference between this and Delicious, Diigo, etc. other than it doesn't have the option to share socially. Since I don't use them socially anyway (though I guess my links are aggregated - whatever), I see this as effectively the same. Of course I am moving further and further away from using bookmarks at all, but that is another issue. Perhaps this has been addressed in the video, but since that is locked from me, I can't see it. Can you please explain how you differentiate your product?
One thing that I could see your service offering that would be superior to the others is automated link checking to verify good links. I haven't used my Delicious account in a couple years, and only access my Diigo rarely, so they may offer this now as well; but when I did use them, I can tell you this was the biggest pain point with online options.
