Well, here is an interesting poll. In my opinion, the userbase of HN tends to be more open and experimental than the average programmer crowd and that makes these results even more interesting to me:

ps. I used the following quick-and-dirty script to parse the results. You can get the current results by running this:

var scores = {}, name, sign;
[].slice.call($0.querySelectorAll("tr:not([style])"), 0)
    .forEach(function(row, i) {
        if(i%2 === 0) {
            var nameAndSign = row.innerText.trim().split(" - ");
            name = nameAndSign[0];
            sign = nameAndSign[1] === "Like" ? 1 : -1;
            return;
        }
        scores[name] = scores[name] || 0;
        scores[name] += sign * parseInt(row.innerText.trim().split(" ")[0]);
    });
var scoresArray = [];
Object.keys(scores).forEach(function(key) {
    var entry = {};
    entry[key] = scores[key];
    scoresArray.push(entry);
});
scoresArray.sort(function(b,a) {
    return a[Object.keys(a)[0]] - b[Object.keys(b)[0]];
});
scoresArray.forEach(function(a) {
    var name = Object.keys(a)[0];
    console.log(name, a[name])
});
