The signatures are changed every day from a list that I keep. I find something interesting in that, I save it and it shows up later. I have another large list containing 'One Liners'. They are something like what a comedian would sling out there. Some are not suitable for a family type atmosphere so in keeping with the intent of the rules here they won't be displayed, humorous or not.
It is nearly always my intent to educate or learn as I go. Surprising what you pick up over time. If you don't mind I will wait until the list of quotes have been used to post them. Many are political in nature, some are pithy in their content, some just startling in their revelations. They are more effective when you see them for the first time. But these are habits I've developed over the years to be a contributing member rather than a lurker.
What I have found here at this site seems to be some individuals who think, seem to be well educated, and are courteous to a fault. Not that it is a bad thing, it isn't.
