you’re right, my initial reply was harsh, i wish i had waited a bit longer before replying. i hope my points won’t get lost in the rant because i stand by them. i really wish this enthusiasm was spent on other hurdles rather than chasing big monoliths. i don’t want to curb enthusiasm, just move it elsewhere
honestly hashtags is 100% lemmy’s fault: groups/communities are “audience” AP field, lemmy some time ago aiming to be “more compatible with mastodon” made it so that posts in communities get automatically added an hashtag, and hashtags get sent into communities. this is honestly stupid and should be undone, you’d better aim your anger at lemmy devs.
regarding mentions, Twitter-like software needs them for addressing: lemmy implies that replies are addressed to replied-to user, other software doesn’t (you may want to contribute to a conversation without mentioning user directly above). if they don’t mention, you don’t see it, you’ll have to just deal with this. you could cook yourself a client that finds mentions in object “tag” and removes them from the body itself if you care this much
