Well, the use case a friend of mine described was using the voting plugin, where each topic in the voting is a long and complex proposal.
Everyone can submit a proposal (by creating a topic in the category with the plugin enabled) and vote for a month.
Having “contest mode”, during this month, would help with the bandwagon effect.
After one month, everything is reverted to normal, and the winners and votes are public, as usual.
PS: If this was not clear by the category, this is a proposal for a feature inside the voting plugin.
