I usually spend 1-2 hour on Lemmy since I am not a good reader(and also non native) so it takes some time to read all the content I like on Lemmy.
I was inactive for some time because I was busy with my life but I am back and now I try to post and comment more frequently!
Not a lot, I don’t think long usage of social media is beneficial to anyone in the long run, even though I’ve been running a (small) instance for quite a while now.
I have integrated checking social media feeds (just Lemmy and HackerNews nowadays) into my daily routine, usually only happening in the morning and evening. Because of my admin and mod duties, I end up opening Lemmy more than twice a day, but only to check on reports, applications, etc.
