Well, now I have a better idea of who like me (luckily, it seems there's plenty, and I added you all to my friends list... you know who you are)
And anyone who wants to be on my friends list, is welcomed to add me too. Maybe some users don't upvote, but they like me anyway.
I like lots of people here. Not from now, but from my very first days.
...and I also know who doesn't like me (luckily, there were just 2, so... Ignore, and problem solved).
On another note, I could find that most of my downvotes were when I said something negative about CoxVanias. Especially when I was new here.
I never went downvoting everyone that talked negatively about IgaVanias, but whatever, we are not all the same, the forum would be boring if we were all agreeing.
I must have done like 500 upvotings or more since I joined, almost always to people I like when they say something I like, but periodically, I also upvote any post I agree or find funny, cute or whatever.
Now everyone can see it... but I'll still do it.
And I'm also glad that now we are getting along just fine with people that (I see now) used to downvote me when I was new.
I agree with the idea of having only upvoting, anyway.
The disagreement should always be made with a text explaining why you don't like a post. It's not the same as a +1, because that's the same as saying that you agree.
Another solution could be to have no points at all, to just get rid of the respect system... but it's kinda fun to have a score, like in a game.
