Great! The RSS URL bug really annoyed me.

2: the ones that do either only offer the headline and then just a link to the web story, or if they give a full feed, inject ads into them, where you don’t have an adblocker to stop it

Thunderbird mostly solves this since it has a built-in browser and uBlock.

Agreed on 1) the lack of RSS feeds. Lemmy also has a problem that RSS feeds aren’t federated, so commenting on new posts is very clunky.
