I'm new here, and I hope to get better acquainted with the folks in here, but I'm not sure that "being single >30" is enough reason to hold a group together. I think these places need an anchor-topic, to work.
Ten years ago, I was on a much smaller "Christian Discussion" forum which was a Tab on a Y2K web site. The Christians that met there ministered to the "seekers" (and, yes, even the atheist antagonists) realizing that that little place was perhaps the only "church" they might ever attend. Oh, it was a wonderful group! We prayed, privately, for them, by email and talked on the phone, now and then. Three of us became such good friends in there that we met once, in person, in Montana.
Honestly, I talked with that group of about 30 people on-line more than I did my own family, in those days. It was a terrific experience; forced me to really dig into my Bible for biblical answers to questions from people who did not even own one.
But it probably worked because it was so small... not so spread out, like this place is. It's hard to keep track of others in a place this large without feeling like you're "stalking" someone whose posts you enjoy reading, for example. I'll bet the people who've been here the longest will tell you that they maintain friendships with only a handful of people.
