Came across this nice little service to send out polls in your Twitter stream. The service, Twitter Polls, is offered by PollDaddy. It is pretty straight forward to use. They provide you 110 characters to ask your question and allow you to have up to 20 answers. The service is offered in 30 plus languages. You can see my test poll at http://poll.fm/psjp.
Tip: Each poll gets an unique landing page that pulls in your Twitter bio. The Twitter profile link and the bio link are both DoFollow links.
