I'm a seasoned internet user (though not a seasoned blogger) and to me, I find Hive a bit difficult to use. Notice I don't even have a profile picture? I've tried to change it multiple times with no success, my posts are kind of everywhere, etc.... I've been here a few months already and to be honest I'm still not 100% sure how to use this site. It's just not like other sites, heh.
I think that's maybe why people leave.
