I'm currently experimenting with a poll creation feature for @botkit. If this experiment pans out, the feature will likely be included in the next release, BotKit 0.3.0. So far, so good. Each vote will trigger a Bot.onVote event in real-time. This could open up a lot of interesting possibilities, like a bot that uses emoji selection for one-time authentication.

Here's a working-in-progress pull request: https://github.com/fedify-dev/botkit/pull/8.
