If you've been wondering which candy your Twitter followers prefer -- Red Vines or Twizzlers, -- the social networking company has your back. Starting today, the micro-blogging service is rolling out its poll feature to iOS, Android and on Twitter.com for desktop. Now users can embed two-question ballots into their tweets. Each poll is open for 24 hours and all votes are secret. So, no one will know about your secret love of Twizzlers when you live in a Red Vines family. When the poll does expire, everyone that participated could potentially receive a push notification of the results. The service looks at your current alerts and judges if poll alerts will overwhelm you. Those alerts could compel users to launch Twitter for something other than a 140-character tirade about the new Star Wars trailer and that's exactly what Twitter is looking for.
