Whether online or offline some of us tend to be more listeners (readers) than talkers. As such, especially on a forum, I am more inclined to speak only when I have something worthwhile to say. Personally, I find many posts to be a waste of space and a waste of time to read because they add nothing to the "conversation."
Having said that, I must add that some of the funniest stuff is on this forum. I really enjoy the goofey humor. You people are smart, sharp, and often just plain silly. I love it.
So if you don't mind too much, I'll be the quiet 54 year old sitting at the side enjoying the party willing and happy to speak when I feel my comments will educate, challenge, inquire or potentially produce a smile.
