Why? Honestly - if you're shipping version 1 the only people that are going to care are people who know what twitter bootstrap is. That's less than 1% of 1% of the population. So why spend precious time catering to that group? Did you check whether the site works in IE6 too?

Also the "hero banner" or whatever it's called has some serious artifact issues. It looks almost like a magic eye

Heh, my photoshop skills are sub-par. I've been putting off replacing the banner with a more robust site intro/overview, sounds like I need to make that happen.
