No one has said anything about this to me, and it's not really something I put all that much thought into, but "tags" seem to be something of a hot topic for discussion or The Discourse, so...
Would anyone actually like me to use more tags, specifically making tags for my various Original Characters? If I did it, I would make the tags obnoxious in some way in an effort to make them unique, since a lot of the character names aren't really so.
If it's not something y'all are really worried about, then I might not, either. I kinda got used to the assumption that I was posting to the Void when posting on webzones that were personal pages, so "discoverability" isn't something I really think about. Also, Cohost feels more like a blog-type space than a gallery-type space like zeviantart or pixiv, so that kinda just makes tags feel like a jerry-rigged stopgap rather than a real solution.
I made/remade/reactivated(?) a Newgrounds account a while ago, one of these days I need to actually take the time to put stuff there as a possible replacement for devaintart.

♥️ I saw someone with the username hamstercorp on there so maybe that was it
