http://forum.tip.it/viewtopic.php?t=269556~100 people have posted in that topic. These forums have had over a hundred thousand people register for them. Firefox is sitting at about 10% market share worldwide, but for a tech-gaming-orientated site like this, I'd guess we'd probably have 15-20%, maybe even much higher. Even if we only had 10% of Tip.it forum users using Firefox, that'd still be 10,000 Firefox users - considerably more than the 100 who posted in that topic ;)
