@caribou,
I consider that the new a2k gives me freedom in reading selection.
I have chosen no minimum and search new posts.
I do vote threads down, for clarity in wading through pages of new posts.
Thus many threads I am not interested in are collapsed for me, all riddles threads, for example. I am not opposed to riddles, I am just not interested in following them, and they and a lot of word game threads clutter my view of the boards. I sometimes collapse threads I'm just done with.
I consider that housekeeping.
I vote down a few threads written by people I've read for years and find incessantly illogical. I also leave up some such threads, because of the nature of the arguments that can see taking place, some of which I learn from re 'how to argue', one of the reasons I follow a2k.
I'll call this clearing of belligerent incessance, when I do choose to clear some.
I often leave threads by people I disagree with since they are started and maintained by people with logical minds in general who are capable of good arguments, some of which can change my own thinking from time to time.
I often collapse threads by people I generally agree with but express their views obnoxiously. (I haven't collapsed my own yet, but since I can be obnoxious, the day is coming.)
I often collapse threads about a subject I've seen argued over and over for almost six years.
I put on ignore a selection of people, some of whom are on a time out for having a rant week if I've heard the rant again and again.
I put a person on ignore whom I have listened at length to the argument of on the rare times it's coherent and sometimes agree - because of the general incoherence.
I put a person on ignore that I sometimes agree with, disagree strongly on one issue, and see future infinite harping on that issue. (I consider this a time-out, will check periodically re the harping.)
I've put a person on ignore who annoys me by sometimes constant thread interruptions, even though I often like digressions - I seem to have a limit for that. (This is likely just a time-out.)
I collapse individual posts for troll-ness or high insult value on occasion.
None of my thread or post collapses are primarily because I disagree with the person; they have to do with behavior.
If you choose No Minimum, you see everything I have collapsed.
