I've never understood the popularity of Slack for investor communication (admittedly not just Tokes but many other projects).  It seems to mainly consist of making developer posts invisible unless going through a major nuisance barrier.

An extra login is a pain in the rear to spend time creating and handling.  Most of us already have tens to hundreds of other logins.  Besides, so much as typing a password is an annoying waste of time.  A better alternative to Slack already exists for public updates: the bitcointalk thread, visible without login each time.
