We have "front," which shows the most upvoated threads...and that's fine for seeing where the community is united. How about a "controversial" button, which would show where the community is most divided?
One of the things I hated about reddit was the samefagginess--how people would throw up posts that basically said "look at me! look at me! I'm doing the thing you guys think is cool!" The way things are set up, it's no wonder they live in a bubble--if you don't like something, clicking a button makes it disappear.
But there's a whole class of posts that are really interesting because they strike a nerve with people, and not always in the same way. Take abortion, for instance: it's about a 50/50 split, and most people have a pretty strong opinion on it.
Polarizing is interesting.
Honestly, you can learn a lot when reading opposing opinions on something, especially when it comes from people that you otherwise share a lot in common with. If there is one fundamental difference between Conservatives and Liberals, it's that a Conservative can hate something yet accept that others should have a right to do it. If a Liberal hates something, nobody must be allowed to do it.
Besides that, threads where people are pissed at each other are just hilarious ;)
It would work like this: threads that have the highest number of overall voats but are hovering closest to "zero" for their overall score will rank higher. For instance, say you have a thread about "Net Neutrality," with 50 people upvoating, and 50 people downvoating--that would rank higher than a thread with 10 people for, 10 people against.
In the case you have something like 51 for, and 49 against--that leaves you with a difference of 2. Divide 2 by the total number of voats (100 in this case), then subtract that percentage from 100% and multiply it toward the total number of voats--that's the overall score for ranking. So in that case, since you would have 100 voats * [1.00 - (2 / 100) ] = 98 voats.
Everything else would be the same--ranked by the most controversial threads of the day, week, month, etc.
