definite room for improvement. Those statistics are much higher due to the large number of developers viewing the site compared to your average site.
Firebird and Mozilla are really making ground though in general - I for one barely touch a Windows computer these days without leaving firebird (and Java) installed

I'll try and update those stats every few months

One thing I thought was unusual was that I couldn't find any querky google keywords used to find the site (except for someone who may or may not be stalking Java Cool Dude

)
Will.
