Online conversations generally tend to be somewhat like conversations you might have with people on a very long train journey or similar. You chat about stuff in general, but rarely about stuff of any great meaning or import to you.
On another forum I inhabit however, this is not entirely the case. Some people know each other personally and I have been there for many years so I know a few of them fairly well.
On this forum, I'm new, everyone is a stranger and I don't assume anyone is going to be especially interested in anything I might say, at least until I've been around for a while and people have had a chance to determine if my comments might have any value.
On top of this, I tend not to take terribly seriously anything I read on the internet! :)
