If a livejournal user replies to a journal entry and asks if you'll add him or her as a friend, under what circumstances if any do you agree to do so?
I'll always say yes. Hey, the more friends the merrier and it's not like there are nuclear secrets in my journal.
Never. My journal is pretty private and I'm not gonna let some stranger read it.
I'll check out their profile and journal first and if I like what I see, I'll okay the add.
I'll only say yes if a mutual friend says that they're okay.
I'll say yes if I like their profile and journal unless there's a big age difference. That makes me uncomfortable and I always say no in that case.
I don't have any rule I usually follow, it depends on my mood at that time.
For me the important thing is common interests. If we have some, I'll probably add them, if we have none then no way.
I have a criteria I used to decide that isn't on this list. Maybe I'll tell you what it is in a comment below.
