Indeed, real-time chats are a horror. A blight that should be removed from the organized collaboration world.

I would rather use E-mail, if only there was a FidoNet-like culture of using it properly among the users and the E-mail client software authors (that would enable proper threading and include quoting only the particular parts you answer).

IMHO the best communication format is a HN-like comments thread.
