Unfortunately since my whole career has been in tech, I've seen such products come and go since they find mass adoption impossible. Question is more like if I'm learning a new language (Duolingo or R/Duolingo on Reddit), playing the guitar (guitarchords, discord servers or R/guitar equivalent on Reddit, or any other niche activity like voice chat (Clubhouse), why would I go to an entirely new platform as opposed to an established, age old space with answers, like even Quora had to reinvent itself quite a few times. Might be just me as a power user in tech, maybe my response is not as valid, but I've spent my whole career seeing Twitter born and launch, Orkut, MySpace, Discord (when noone knew it), Discourse (remember them? Great product, no adoption), Telegram (several crypto groups use it as default since many years), etc.. Guess my answer is more like don't reinvent the wheel if it's a long term goal for you. If it's a fun side project for friends and fam, go for it. It all depends 🤓
