Go for it. If you get a million Up-Voted, then I'll know for sure someone has been down voting my stuff. Look at my home page. Look at all my work. Look at the vote counts. Does any of that even make sense?
The problem with this site is getting views. Most of my memes also have too few views as well. If you are not getting views you're not getting any chance for a vote. Unless you've made some enemies I doubt anyone would be down voting you. :)
Enemies? Hardly! I have not criticized anyone. I Up-Vote every comment, and have seen it resulting in ZERO. Meaning there is something negative happening with arrows! I'm here to practice art work, and express myself through posters!
I don't know about you, but I don't always know which of my memes will get the votes. Very often what I thought to be mediocre submissions gets all the votes and the ones I think are real good don't even get enough views to be given a chance or people just simply don't get it at all.
