@Lustig Andrei,
I don't think I ever have thumbed down for disagreement. Maybe, but I try not to do that. Certainly not for random troll play, which we've seen here. Behavior, yes, but I tend to float over it for the zillionth time, or ignore for a rest period. Of course, having floated over something a lot, when I bring it up, like I did on this thread re CI, I tend to get over agitated. I apologize, Tak, for the repetitive battering.
I will often thumb up for well expressed views that introduce new thoughts or data to me, sometimes when I'm in present disagreement but want to think about it, whatever it is. Finn and I disagree on stuff and more stuff, but I've thumbed his writing up a fair batch of times. I will post up for posts that obviously take work, as in finding photographs or useful links. I'll thumb up for very funny. I wouldn't be surprised if hingehead hasn't gotten the highest number of my thumbs up.
I'd say that in general I don't somehow hate people I ignore/send to cloak room - it's more for my daily sense of well being: I am here most days over years now, and that is mostly to enjoy myself, learn, and catch up with a2kers while trying to keep my own real life going in sometimes tricky circumstances.
My ignore list gets elongated since I look at pretty much all new posts and there are some subjects I just don't want to see, and want to do housekeeping to clear. A lot of those are people busy at games and trivia, though I like those sometimes, and from my experience to date, like the people. Some of the threads I don't want to see again are about philosophy/religion/hot air (oops). With newbies on those, I try not to thumb their whole threads down until they get a bunch of people participating - but after a lot of those I will add the poster to ignore.
Finally, to repeat, should the site folks get into a serious redo re the ignore business, I'd like, as I've said or tried to explain, that if they are going to make it reciprocal (they can't see you either), that I'd like there to still be a second type, the rest period type, where the person doesn't have to know. No hurt feelings going on, and the ignorer can change it.
