Upvoted: This thread, because it was posted by Pendragon.
In all seriousness though, these two four five are on a similar topic, so maybe more insight? I can't say how consistent I am with voting, but:
Upvoted: This thread. Seems to offer a lot of constructive feedback, in a civil and well organized format (and OP managed this on their phone! Much points)
Downvoted: This thread. Wow. Much QQ. I honestly can't tell if there's meaningful feedback here since I'm so distracted by all the flame and toxicity.
EDIT: I'll add a few more on the same topic, more data:
Upvoted: This one, same reasons as above, very well formatted and argued.
Downvoted: This one, again, same as before, much QQ.
Basically, if there's something that seems blatantly inflammatory or just poorly structured, etc. I'll probably downvote it. If it's something that's decently structured and I disagree with or am unsure about, I'll probably leave it alone. If it's something I find very well structured, even if I disagree with parts of it, I'll probably upvote it. If it's a cool thing someone made or something that makes me laugh, I'll upvote it. If it's a well presented opinion that I agree with/was about to express, I'll upvote it. A lot of times too, if there's some contrast in a common topic, that'll influence my voting, like with the threads above; I'll be more likely to upvote the well structured posts and downvote the poorly structured posts instead of staying neutral. I think that's relatively exhaustive on my voting habits.
EDIT2: One more for the road; same topic
Downvoted: This one was really hard to make a decision on. When a lot of threads on the same topic come up, I'm more likely to upvote the ones I think are healthy discussions and downvote the ones I think are non-productive. I was mixed on this one for a while; I think Factions is a really great idea, and done some really great work that I have supported on previous threads. There are some points in this post, though, that really come off as too confrontational (like the last part of the title). Under normal circumstances I probably wouldn't vote on this thread, but in light of the previous threads on this topic that I upvoted (which show the range of how a discussion can be held), I think there was a better way OP could have made this post, and that the threads I upvoted would provide/are more deserving of good discussion, so I ended up downvoting.
EDIT3: One other thing; if a post or comment has been downvoted to 0, and I don't think it deserved it, I will upvote it back to 1, even if I wouldn't have upvoted it normally.
EDIT4: Okay I swear this is (probably) the last one: I also vote in relation to my other votes: I might upvote a post/comment to say, +3 since I think it's a good post/comment that deserves more attention, but maybe won't upvote a post at +2 to +3, even though I like the comment, because I think the first post deserves more visibility, and the way the posts/comments are, the difference between +2 and +3 in terms of visibility seems pretty significant. I do this more often for comments than for threads.
EDIT5: I lied. I take into account how many upvotes something has before downvoting it; if it's a new thread with 1 upvote, I might not downvote it unless it really deserves to never see the light of day. I ran out of spa
