There's a GH issue for it. @jimmysong created a pretty detailed request for it a couple weeks ago. I'd say we're ~3 weeks away from me doing it. There's a handful of other stuff I need to do first ... Assuming a new fire does not start in the meantime.
I think polls would be a really cool feature, you could do interesting things like the winner users get a portion of the sats that the losers of the poll forfiet lol
