The blog went silent b/c Christian was put in charge of everydamnthing at the OKC office as Sam (the old CEO) moved up after the acquisition. I don't think there was any pressure from management, which would have been dumb -- the blog was a great asset to OKC/Match aside from that one post that they deleted for obvious reasons.
(Source: I used to work at OkCupid Labs, one of the things that Sam went on to do under Match, where he is now CEO.)
