I post on a local Austin messageboard called
www.groovetx.com.
At one point, I was but a newb. Since I was so into the site, I got all my friends on it. Then I became friends with people from the site. Since being on there for years, I've met almost everyone that posts, and everyone that posts is good friends. There are a few messageboards that are Austin based that I post on that are very similar to that exact situation. For my friends and I, messageboards and computer communication have become a way of life. All the past 5 bfs I've had, I've met online first. It's just another way of meeting people. It's no different from any other setting really.
And no, I don't think about it anymore. You're just coming of age, dear. When you're not a teenager anymore, you'll understand. Life isn't TOO complicated. No need to go around asking "don't it make ya think?" about everything.
