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!
10h 14m total in the last week, according to my phone. So a bit more than an hour a day on average.
