“CommandShift3 is like Hot or Not. Except, instead of clicking on hot babes, you click on hot websites.”
A very straightforward concept and one that has definitely caught on with a bunch of people. One of the neat things they've done that I like, is the video you see when you submit your site. They've conveniently compiled a list of all the videos for your perusal. Ben Brown and Taylor McKnight are probably my two favourites of the list.
Beyond that, Elliot Jay Stocks got asked to put together a special video for their 404 page. I left a comment on that post about doing a video. Lo and behold, they saw the comment and asked if I'd do a video. (See, it never hurts to ask...even in an off-handed way.)
If you'd like to see said video, try to find a page from the unknown. You may have to refresh as it'll randomly choose a video between myself and Elliot. (And yes, I bought a webcam just to do this video. Although, trying out Ustream.tv and Y! Live has been fun, too.)
