Yes, I know about hashtags. I use them. albeit sparingly, as I think is appropriate, without making my posts #look #like #Ransom #notes. For example, I tag my photos with "#photography". What I won't do is label my "boring" posts, because I like to think that every one of them has the potential to be boring to someone.
@mattblaze What Mastodon needs is pre-read video clips where posters can do an interpretive dance describing their post, indented audience, possible folks offended etc. ¯\_(ツ)_/¯
