Yes I agree. I can see how a topic can start to wander. Being a new member, I experienced just what you discribed when I was surfing topics I was interested in. Its a nice freedom to be able to share this and that, (kind of like show and tell in kindergarten) but the post loses its line of main info. Maybe if we have astory or experience to share that is off topic in a thread, we could share it by private message to that individual? Its always nice to get a message!
