According to Wikipedia (2/5/11), "MetaFilter was founded by Matthew Haughey in 1999. Haughey wrote the software for the site himself, using Macromedia ColdFusion and Microsoft SQL Server. From its early beginnings as a small community of webloggers who traded links, the weblog now enjoys international popularity. Members are permitted to make one post to the front page per day, which must feature at least one link. Members may then comment on these posts."
