@eris so it’s a vestigial linguistic structure persisting beyond its relevant context, interesting
What the heck is vestigial about it? And why do you hate it so much? One can find pertinent things through hashtags here, and one can scarcely hope to find them any other way.
@mxchara @eris even searching for hashtags doesn’t work here on akkoma so we’ve all just given up on search, I forget it still matters somewhere 
@mxchara @eris and it’s not that I hate hashtags in themself, there’s just this particular kind of guy on mastodon instances who replies completely missing the point and adding like 10 hashtags at the end of the post
