MetaFilter - Happy 12th Anniversary!
The site was originally put together by Matt Haughey and frequented by techies. There was a lot of discussion in the early days about web design and development. Adherents of Jacob Nielsen and web designers would trade barbs particularly over the use of Flash (hence the 'Flash Wars'). This was a dispute not settled until the arrival of more reasonable adherents of usability like Jared Spool who knew how to speak to designers and thus had a far more positive impact.
Later on as membership grew, topics of more general interest such as news and politics became more prominent. MetaFilter was where we went to discuss the fall-out from the Bush-Gore election results in 2000 as well as the aftermath following 9/11.
Anyway, the local alternative weekly where Matt Haughey lives in Portland has run an interesting article on him called, "The Blogfather". Also, MetaFilter has its own page of user-submitted reminiscenes called, "MetaFilter Memories".
