it's not life that matters but the journey...

Hello! I got here through your comment in goffburd's journal. :)

Have you tried any addme communities? Lots of the people there are in their 20's and under, but there are some older ones, too. I know for a fact that Harry Potter fandom at least has a lot of older fans because I remember that when I got into the fandom in 2001, most of the active people were older than I was or around my age (21 then). I would guess that Supernatural fandom has older fans, too, since it's such a big one.

fandomsecrets has sometimes got friending posts, you can keep an eye out for them or browse through the old ones to see if there are people you'd like to contact. You may have to scroll far, though, as I think it's been a while since the last and the community gets updated daily. Communities in general are a great way of getting to know people.

You can also do what I've done a couple of times; search for people by interest or location, check out their profiles and journals to see what kind of people they are and when you find some you like, just ask if they're interested in new LJ friends. Some probably aren't, but you may find a few who are. Just make sure to comment instead of randomly friending people who don't know you from somewhere. :)
