Firefox takes the lead!

I just realized that Firefox has taken the lead for the first time in browser market share per w3schools.com. It may not be the leading authority on browser share reporting but it seems pretty accurate when I compared it to some other sites. However, some sites like hitslink.com seem to have a definite bias towards IE. I can't believe that Firefox is that low on the list and IE still that high when all the other sites are reporting much more equal numbers and my own experience is saying the gap is closing.
