Thanks. I'm rather disappointed that someone demoted my post from main to to discussion last night - whoever did this did not identify themselves to me, and I am curious as to why. I have not yet gotten feedback regarding this or the down votes.
There have been a lot of up/down votes, which I find quite interesting, and as with yourself, would be curious to know more about. Unfortunately I didn't take tallies while watching it jiggle yesterday and I don't know of a place to access actual numbers, but I believe that it was up/down voted somewhere around a 7-15 times each direction before getting to its current state of 0.
The article is currently at 52% positive, with one upvote showing. I think the smallest number of votes which could produce that exact result is 51 positive, 50 negative.
There has to be rounding, but (looking for vaguely plausible numbers), it has to be between 67 positive, 66 negative and possibly as low as 41 positive, 40 negative, depending on how the rounding is done.
Given my druthers, I'd like to see a graph showing the votes over time.
A post that achieves a high number of votes in both directions strikes me as a very interesting post that should be called to attention. In other words, a post that is at +/- 1 because of 50 or so votes each way, is much more interesting than a post that is at +/-1 because of one or two votes.
I would recommend rather than showing just the sum, show the total of both +1's and -1's separately. It's strictly more information than just the sum.
Seconded. StackOverflow shows this information, and it's frequently interesting.
Would you mind pasting a link for this? I'd love to know exact numbers.
Sure. Here's the most-viewed question on SO: http://stackoverflow.com/questions/11227809/why-is-processing-a-sorted-array-faster-than-an-unsorted-array
If you click the score on the left, it splits into green and red, showing up and down votes respectively.
Interestingly, there are very few down-votes for such a popular question! But then again, it's an awfully interesting question, and in SO it costs you one karma point to downvote someone else.
I agree. Reddit has a "controversial" sorting that favors posts with lots of up and down votes, and I prefer to use it for finding interesting discussions.
My calculation gives possibilities of anything from +11-10 (52.38%) to +17-16 (51.52%), assuming the displayed % is rounded to the nearest whole. It now stands at 4 and 56%, implying +18-14, +19-15, or +20-16.
Thanks. I wasn't sure I had the math right.
More exactly, it's been a long time since I've done much algebra, and it was a fight to get any sense out of problem. I had a feeling there was something I didn't understand, but I had no idea the weak spot was that the rounding off range didn't include the exact percentage.
Finding out how much a single vote changes the percentage of up or down votes gives a lot of information, and this can be learned by giving a vote and withdrawing it quickly.
