as i see it:
#need-help: how do i do X (includes advanced questions)
#getting-started: how do i do X (excludes advanced questions), but also introductions, sharing blog posts/articles tutorials about getting started
#general: anything (related to kotlin)
it's not really so much a problem that there isn't a place to ask/share, but it's not clear which channels to use
(also, most slacks i'm a member of have renamed "general" to "announcements")
