If I'm going to prefer Mastodon over Bluesky I need to:
1. Find a good host to run my own instance (otherwise the federation benefits don't seem quite so beneficial); recommendations welcome as I don't have the time to self-host
2. File a feature request to make it easy to take your filters with you when changing instances
3. File a feature request to make adding to your filters as easy as it is in Bluesky
