I'm totally with you. I feel as lemmy develops, we'll start to get more QoL. I've been having the same issue with not being able to post comments on random posts, and I have my own self hosted instance. I think it has something to do with the instance the content is hosted on being overloaded? Not sure how the backend works, truly.
What would also be kinda neat, is if I could eventually transfer my instance over to a kbin instance. I quite like the idea of being able to track my thoughts and experiences via microblogging, and I'm not sure if I want to have a seperate mastodon account for that.
Homer's Triple Bypass. Got it. I'm making a list of episodes to pay extra attention to, as recommended by ya'all here on lemmy. Great recommendations so far.
