Pikipedia has a poll system, where a poll will be shown on the main page for users to vote on. These ballots can range from trivial things, like what the reader's favorite leader is, to useful, interesting, statistical tools, like comparing the number of players that use certain control schemes.
The polls are updated every two months. To help decide what will be the next poll, editors are encouraged to add and vote on poll ideas. When it's time to switch the poll, a trusted editor is tasked with choosing a poll from the nominations, and communicating with the community to settle tie-breakers and what options to add. The poll is created on crowdsignal.com, and is then updated, with the previous poll being archived (but still opened for viewers to vote, if they so wish). Detailed instructions for the editor tasked with updating the poll can be found here. More details on a poll's lifetime can be found at the policy page.
