  > often there doesn't seem to be a dedicated support channel/community

That got me to post in "issues" a few times, while apologizing and pointing out they should have a forum. It's so easy too: Just create a new subreddit (or use an existing one) and - that part is important!! - point to it as an official channel. Flow(type.org) is an example. Their "support" links are: SO, Github issues, Twitter, IRC. All of them are very bad for discussing general usage questions. If your question isn't already very well formulated and very specific, with code, SO will downvote and close your question. IRC or any chat mixes everything and it is about that particular moment, it does not collect people's responses over the course of a day or two.

Oh and please don't create your own forum. Almost all forum software sucks. As much as one wants to complain about reddit, their forums work, and I mean the technology and design and usability. There is a Flow subreddit, but since the Flow support page doesn't point to it it's pretty empty. Flow is just an example.
