I have noticed that, too; of course I am one of the ones who is not too contributory, but sometimes, you just don't have anything to say that might be of interest to others. I won't normally discuss politics, religion, child raising, or personal hygiene, and no one wants to hear me complain about my lot in life, I ain't gone shooting, of any sort, in a long time, -------------- so, I just drop by a couple of times a day, and if I think I can contribute something to a subject, or have a mundane bit of news I'd like to spread, I will; but otherwise, I'm keeping my trap shut.
