Wordpress.org has a bubble very near the center, north-northeast of Google and west of Facebook. It's much nearer the center since that's where all the linking and blogging happens.

Out in the void to the northwest is wordpress.com. This appears to be a freemium service based around Wordpress the software. Presumably this one is far out because there's fewer links and connections to it, and presumably only by those who find the .com first and don't realize .org is the "true" Wordpress home.
