Yes I have, but I have to remind myself that they have added way more content than they expect one person to engage with, and its on purpose. YOU know best what you are intrigued by and interested in, and for large open worlds can ignore as much as you want, but if you are enjoying yourself chasing the threads you find engaging then they have succeeded at what they set out to build.

If it works like email, you'll miss content that is posted when the app isn't running. I have a cheap hetzner box going that is running my personal lemmy instance but I don't think it would work well to have it only running part of the time.
