I've been spending more time on Discord. It is replaced forums and subreddits for many of my interests like synthesizers and music. I don't like that the information is stored in a chat-style vs posts.
It's barely searchable on their native search bars too, and with no scoring or back-linking possible you're stuck searching chronologically. That's only viable on a small enough channel + keyword so that results are limited. Otherwise you don't search, you just ask again.
