What I would do is I would make sure that all the "or"s on the page line up. Then, I would change each line from being one link to being 2 links, so that the "this" and "that" are both links; clicking on one of them would result in voting for it.
Once you vote, you can turn off the voting for that line (via js).
I get an Internal Server error on any link I click.
But to be honest, I probably wouldn't have even bothered trying to click if I hadn't visited the page with the specific intent of giving the app a try to review it for you. It's just way too much text, with no real rhyme or reason for why it's presented the way it is, and no real incentive to do anything but close the browser. I agree with mediaman as well: voting should be possible without need to click through -- think of another incentive to get people to click through (like commenting/debating the merits of the head to head).
nice first web app. you will be contending with the myriad of "hot or not" type clones that largely cater to the unmonetizable idling office worker or bored-to-tears slacker.
500 Internal Server Error when I try to vote either way on anything. It does not appear to count the vote.
I am not accepting cookies (except from explicitly allowed sites); this might be related. If so, the resulting behavior should be something other than 500'ing.
Randomize the left and rightness of the choices, and make the "or" centered (make it a 3-column table). Otherwise you will have heavy right-hand bias in the voting.
It seems to me to be a little difficult to see whether 'a' or 'b' is winning, with the vote number in grey. Maybe the text size could increase with votes.
I am addicted already! Great simple concept. Others' ideas about the plainness and being able to vote without going to the sub-page are spot-on though.
Also, it is kinda boring and just too much of a word blur for my tastes.
It kinda has also already been done in a way by sites like http://www.googlefight.com/
