I recently had to deal with some Discourse users trying to hijack my community's discussions to a Discourse chatroom. Absolutely awful experience and terrible client support.
I like to think of Discourse as the "long term memories" in Pixar's Inside Out. You ship stuff there as you need to. A mixture of mostly short term and sometimes long term memories is a sane and manageable arrangement for most humans.
I'd be interested to understand what you ran into in more detail.
