At VMware we use SocialCast[1] (not sure if we used it before we bought them or not, that was before my time) and it's certainly used in a "meaningful way". Not everyone in the company uses it regularly but certainly more than enough for a sufficient critical mass that if you have a question you can ask it in the appropriate group(s) and you'll most likely have an answer within hours (and often minutes).
