certain topics initially open the door, others drift into .... along the way.
once it drifts, I typically follow along for a few reasons (ignoring or discovering idiots if they pop-up)
1. it might get back on original topic, further wisdom to gain
2. exposure to different opinions. the status quo surrounds you but you cannot imagine the ’other’ unless it finds you, or you seek it. ’East Village Other’ an example from the 60’s.
3. Fuller understanding of other members whom I have come to respect.
4. a chance to pass on who I am to others, if they care, then my comments in threads can be understood ’better’.
