well, the discord community is quite big. it depends entirely on the kind of folks you want to attract. you are right - if its the office going devs, management folks then slack maybe the right way to do it. although we have a slack at workplace but the gamers in the office we use a Discord server. so far has been easier to pull in folks there since the context is preset - you are joining because you are working full time and like playing games (namely Factorio for now)
