I've always viewed the HLP forums as a sort of "info dump" - good for getting lots of information in one place. It's somewhat clunky for actual, active conversation, however - it used to be the norm for us to edit our posts instead of double-posting, but the latter seems more prevalent these days, especially in really active discussions.
This view has a flaw: what's the Wiki for then? Does it share the same purpose as the forums? Is the sort of information there different from the information you can find on the forums? And given this community, it's definitely not the ideal place for any serious discussion.
For active conversations, we have the Discord. Between Matth, Nyc, and I, we've sorted out two double-edit embarrassments I've made on the Wiki over the past year, and it is they, not me, who took the initiative to contact me on Discord, rather than on the Wiki itself, about it. Granted, this may be because we use Discord heavily, but if two people from two different countries, cultures, etc. with two different issues chose the same option to settle their issues, it may be a rough indication that the Discord is a better place for more active conversation.
