Hello old-browser-using friend! Despite the mid-2000s aesthetics here, this site is actually built mainly with modern web technologies. So, if you're not using one the site will probably look broken.
I try to make it work as much possible where the fixes are simple, and the site shouldn't be so broken as to be unusable (let me know if it is) - but my sanity and experience for modern browsers trumps supporting IE7 or whatever.
