Yeah, I think you have a great site, but it's not quite there yet. One thing I noticed, when I hit the pause button, there was no indication that it was paused. Maybe the pause button could change colour when someone clicks it? It seems like a good idea, although the sites do change rather quickly
That's intensely annoying, how about wait for the user to search rather than stuffing 800 websites a minute down their throats that they're probably not interested in at all?
