I have a version of myself aged in their twenties and working in web development that really wants to stab anyone believing that IE6 was the best browser.

I won't argue that it wasn't decent at launch, but MS kept support for that browser around way too long and failed to actually roll out support for new features that customers desired. I believe it was the era of IE6 specifically that led to the proliferation of top-right-corner.jpg which was an absolute abomination.
