I use Matchups as a username all over the place, including my domain www.matchups.com which I later sold. The original source was a Scrabble newsletter I edited, which was an ironic comment on "matchups" not being in the official dictionary.
My main interest (from the Wiki point of view at least) is games, and bridge in particular, though I spend most of my time these days being a wikignome.
As of October 2013, I have 4234live edits. Though most are small, nearly all have edit summaries.
