Twitter, which has been adding new features under the leadership of interim CEO Jack Dorsey, is introducing a tool that lets users create polls and track results. Anthony Noto, Twitter's chief financial officer, started posting tweets on Thursday with embedded polls, including one that asked: "Boxers or Briefs?"

Aly Pavela, a spokeswoman for the San Francisco-based company, said, "We're experimenting with a new way to poll users on Twitter."

Twitter is by no means the first web company to introduce online polls. Facebook and Google give users the ability to create polls, and SurveyMonkey's business model is based on online polling.

The new feature is the latest to be bolted on to the social-media company, which has been looking for ways to reach more people and boost user numbers. So far this year, Twitter has introduced a service for collecting political donations, a buy button for tickets to events and an app for streaming live video, called Periscope.
