*sigh* Just read a thread where it looked like the poster was arguing with invisible people. Turns out the whole thread was auto-reposted from Twitter, so we're seeing just the poster's angry responses to the ignorant (and, to us, invisible) replies they got on Twitter. This is an unexpected side effect of auto posting: A peek at Twitter Rage that I really did not need to see on my Mastodon timeline.
I'm begging you, folks. Commit to one or the other. Don't Twitterize the Fediverse.
