I don't think that sounds very weird. Message boards can become a compulsion, but at least they are an educational compulsion that does no harm to your liver or affect your driving.
Before I discovered message boards I spent too much time and money on ebay. I was surprised when I first started posting on one about 3 years ago at how fond I could become of people I engage with on the boards. Also how much you can come to know a person via the printed word. And also, how fulfilling a cyber friendship can become regardless if you ever meet in real life or not. I think it might be the immediacy, the daily contact and the group situation that makes cyber socializing so much like real life. Or more like real life would be if we actually lived in close communities where we saw each other daily and had interconnected ffriendships. It's a phenomenon that still amazes me after 3 years.
