If everyone was as giving as you @jaynie, this would be a much different platform, but from what I can see, there's givers and there's takers, and there doesn't seem to be too much middle ground.
It is something I do not understand either! Even people like myself, with very little SP of my own, can give and interact and help others. We all are in this together, so the fact that many 'bigger' folks don't do the same is a mystery. I've been on the receiving end of a 1% vote and have thought the same...why bother?
Thanks for the great post and for all that you do for everyone :)
