The mistake with the previous theme poll wasn't many choices, it was single voting. Besides, I think we can agree that people were a bit unhappy when you went on to change the theme.. I think you should have just left it as it is, but, oh well.
On a side note, I didn't really like the themes you kicked out, I'm just looking for justice for everyone. And if someone proposed doodads then, he might feel kinda bad. What if next time we said "well Diablo theme is lame, so why not get rid of it?" or "well who wants Steampunk?", you never know. Anyways, not a big deal, I just like perfecting everything I guess... In fact, if you ask me, I think we could use Preferential Voting on this matter, but some people might find it too complicated...
