I only use my livejournal for communities. I've tried the entries/lj friends thing with another journal and it just didn't work out for me. It became more of a chore to update, read/comment on the bazillion strangers' posts on my friends list, etc. The people I know offline don't use lj. I tried to introduce one of my friends to it but he signed up and then did nothing with it. :P
Also, anyone else do this or felt the chore thing? I enjoyed it at first but at this point I just don't feel like trying it again. I know I could try again with just adding people who really interest me and don't mind being added but I just don't feel like updating a journal right now. Don't know why, because other than that I normally like writing.
