Same for me. All types of non-async communication is mainly a time eater. Good to quickly coordinate stuff, but only for a core team.
(I had joined slack & discord now, to find out if anyone understands the pump, but I can not afford to be there often I guess).
I understand that from the low volume in this thread you had assumed "no one" is reading it, which is not true for me by the way, I had been here often, checking what is going on.
I have been checking here on this thread often too. Here the the public can view all the content without logging in. Not for Slack.
