It's interesting (and sad) how the forums of yesteryear have essentially gone away entirely, with no good solutions popping up to replace them. I know they were/are incredibly prone to security issues, but they were good at one thing and one thing only: community.

I recall spending a crazy amount of time refreshing the index on a site called TradeGamesNow (and to a lesser degree CheapAssGamer) waiting for new posts/comments. Now every site on the web either has a Subreddit (too much tertiary noise), Discord (I'm terrified of making a post on the wrong server by accident), or (to a lesser degree) Slack (limited features, as noted in the article).

As to the Slack announcement: I get that guests staying in your house for free eat not-free food. That being said, I have to imagine that Slack could offer a non-real-time updating experience (no polling, disable calls/video/file hosting) to cut down on costs (my assumption is that the active nature of the service is the biggest expense) and make it feasible for a free or $5/mo for X users & unlimited guests.

(I'm aware that Discourse was Supposed To Be The Chosen One, but at $100/mo and no self-hosting option (that I can see), I don't think it's even considered much. But I could be wrong.)
