tags have multiple purposes here on the ol' cohost:
- making posts globally searchable (major use of fandom tags for example)
- additional commentary that's not visible via rehost in the tone of an aside
- filtering content (eventually)
- personal organization of one's own posts
the latter two are, to some degree, in conflict. this is particularly the case for things like jokes, goofs, or other chortlesources. I may want to be able to get a list of all my shitposts, but it kind of ruins the tone of the thing if I am in effect saying "#shitpost" to the audience after I finish whatever awful joke I've made. so I wish there were tags that only showed up for me.
because this is a kind of narrow use-case, I think it might make sense to have it work by some sort of "magic prefix" for which tags don't show up publicly or in search. I might write "#priv: shitpost" for example. this gives rise to the idea of other special tags, but that's left as an exercise for the reader
Edit: People seem to like this idea so I made it an official feature request
