The CMs are expected to talk

No, dear. The CMs are expected to talk all over the place and we love them for that. They're our liaisons to the game devs and provide Blue forum posts for everyone.

We're talking about the game developers and others that people follow on Twitter to wait for some or world of Warcraft tiny tidbit of "inside information". They're the ones who may read a quick twit question and write a quick answer, while waiting for things to compile, load, etc. (read what Lore wrote, gosh).

But they agree that dropping work tidbits and releasing info on Twitter is not good business practice so they're going to curtail that behavior.
