as a general PSA: if someone only provides a Mastodon or Bluesky account to follow and you don’t want to make an account on either service, don’t despair! you can still follow their updates via RSS.
Mastodon (at least by default) lets you put “.rss” on the end of a profile URL to get the RSS feed, e.g. https://mastodon.social/@GFD.rss. Bluesky seems to use some kind of internal ID in the RSS URL, but it should be discoverable from the profile page; i use the Feed Preview Firefox extension to find them.
tumblr also has RSS, and even provides RSS feeds for individual tags! [USERNAME].tumblr.com/rss for the full blog and [USERNAME].tumblr.com/tagged/[TAG]/rss if you'd like to follow just their art or webcomic updates or what have you
bluesky/tumblr accounts set to private/18+ don't share their feeds, unfortunately, and pillowfort doesn't appear to have any kind of syndication
i'm going around today hoarding feeds into a free inoreader account; they're also capable of ferreting out the RSS if you give it a bluesky URL, no fuss. it can also export the list i'm building today and import to other feedreader services so i'm not locking myself in to anything. since that's, you know. increasingly important to me 🙃
