I'm afraid there's not much more to give you than vagaries. I have personality voted in the past, on you and others, both positive and negative, but I haven't done that in a long while. The vast majority of my votes are spent in a gut reaction to whether I *feel* a node is good or not, based on whatever criteria happen to be fluttering through my brain at the moment. Does it suck, or not? Do I like it, or not? The criteria are always a little different for me; I would venture to guess that the same is true of many others. It's also why I don't explain my votes. This will be the only thread where I ever do that, and I'm only doing it now because I'm tired of it coming up over and over.
