All Rankings is a very, very simple way users can create a poll that allows people to vote on just about anything. There are a lot of polls on the site, but I wasn’t able to find anything inappropriate, so it could be a could place for ELL’s to vote on polls, too.
The major drawback that I see to the site is that it doesn’t provide an embed code, but I’m assuming you could use Embedit.in , a free web tool that makes pretty much any url address embeddable. (Oops, my mistake. After I posted this piece I realized that it does, indeed, have embed codes).
I’m considering adding it to The Best Sites For Creating Online Polls & Surveys because it opens-up the polls they create to a wider audience.
