I've been working on this, along with building a customer development strategy, for about 8 to 10 hours a week since October. I'd appreciate any feedback on the app, the site, and the concept. I'd also like to share the custom development strategy in a later post, if this post gets any traction.
re: youtube and the video filter. The topbar and the sidebar are two totally different things. I think is more than OK for youtube to be in the topbar. In fact I want it there. I click it all the time when I want to move my search to youtube.
