Why here and not Mastodon?

Most of the things I write here are simple one or two-sentence posts that could more easily be posted to Mastodon or Micro.blog or whatever. So why do I keep writing them here instead? Good question. I don't know the answer. I think it's because the things I write here are opt-in. Posts don't automatically show up in some common feed and are not emailed to people. They are included in the RSS feed, but that is a feed of only my posts, and only for those who have actively asked to see them. This may seem like the opposite of what I'm supposed to do. I'm supposed to be spreading my wise and clever words as far and wide as possible. I prefer keeping things in my space, under my control, and out of the way. This feels better.
