Just read this cohost post about a common phenomenon in online projects: Discord servers for help & support, and just service lock-in in general, I suppose.
I specially like this quote:
[...] we've normalized not logging in. At this point, I don't think you can get anyone to log into anything, ever again, unless they believe that "all their friends are there." Whether that's literal - as in a new social network - or figurative - as in "1200 users, wow, this must be a great resource" - the friction of getting someone to sign up has to be colossal in this foul year of our lord.
I've read a related blog post a couple days ago - this one. ("Please don't use Discord for FOSS projects")
Only slightly related, I've been hanging out on the melonland forum, and it's been really fun.
