I've been considering it further and I come back to... validation and being "heard", but also timing of that.

You will come back here to check for a response, your need is to have been "heard" and responded to, after all no-one likes to just talk to an empty room, so to speak. It's a payoff to be responded to.

Then comes timing...
I mean you will come back to check if there is a response and if there was none, you would check some more until eventually you may check just periodically...conditioning and eventually extinction maybe? The board would hold little interest.

So this is the role of a moderator in part? to respond and encourage. Doesn't it apply to almost all messageboard/forums? maybe important to have a number of moderators to share the load in the hope that with increased participation their role would decrease.

Oh the only other thing where you are guaranteed an audience is to mention sex :-)
I've put it in the title of a new topic...let's see if there are more hits for viewing the topic anyhow. I guess I have to see if the word sex is allowed by John :-)
