The stats I am referring to come from a music review site... though there some level of tech related traffic, the majority of traffic comes from music related searches. Granted, this demographic is younger (mid-late-twenties/mean) and more up-to-date regarding tech trends. This most certainly accounts for the reported levels of Mozilla/Phoenix/Firebird, and Opera stats. Lots of Mac Safari action too... (it's GREAT to see Mac users dumping troublesome IE!).
I also get a LOT of traffic from shools.. (darned kids should be doing their homework!) and I can say NN4 is just about gone... Most school traffic I get from k-12 domains use IE6... University traffic runs the gamut.. suprising and welcomed numbers of Moz variations and Opera. Nice to see.
I strongly suspect that the stats reporting very low instances of Opera are actually recording only those Opera users with their browser set to ID as Opera (as I have mine set..), the others are marked as IE and not properly identified.
