I love the whole concept and execution, except I think the tweets should scroll by slightly slower, as sometimes you don't have time to read a tweet before it disappears.
Yeah, it's a tough call. If we slow it down, we'd have to show fewer as the underlying stream is zipping by. We considered pause or pause-on-hover, but sort of assume people will glance at it, not stare at it, if that makes sense. Gestalt, not reading?
Nice! But on a netbook if I reduce the font to try to get both the Democrip and Rebloodlican halves on the screen, the Rebloodlican side just disappears.
