I know lots of folks who want to get off that "do be evil" platform, but there aren't enough users at a comparable site (Dreamwidth isn't comparable) to move. www.mewe.com is, and is an infinitely better corporate citizen. And if enough of us commit to posting everything we post here, also (or only) there, then there will be enough users.
January 1. Put a reminder in your calendar. And spread the word.
