The news started to emerge in various Twitter feeds and personal blog posts Monday: David Recordon, a Six Apart developer and prominent open-standards advocate, has left the blog software company to take a job at Facebook.

Recordon, who formally announced the job change on his LiveJournal, will take on the title of senior open programs manager. "This past year as I've worked closer with teams at Facebook, I've been impressed by their products, smart people, and innovation," he wrote in the post.

It wasn't so long ago that Facebook was seen as the ultimate in closed-off technology, with profiles hidden behind a log-in wall and features built with in-house technologies rather than open standards. At that time, a hire like Recordon would've seemed to many a ludicrous match. But Facebook's changing: it joined the OpenID Foundation earlier this year, made a big chunk of its developer platform open-source, and its Facebook Connect universal-log-in product has earned both developer and mass-market approval.
