Please like the appropriate post. This is a cutting-edge testbed, and in no way a cheap way to farm likes. Honest!
I am innovationing. An innovation has been proposed, and now - clearly! - we must innovation it. Unless this is a shitty idea which would not work in practice. But I can't imagine anyone going to these lengths to make that point; no, sir.
Yeah, that's pretty much your only option if you want to do audience participation polls in an LP thread, since you can't edit the thread to add a poll to it after the thread's been posted.
Well, realistically you're going to get asstons of likes in LP threads anyway; you're really just asking the readers NOT to like the posts they don't want to vote for. So I suppose it could work there. Anywhere else, and it's a terrible substitute for editable polls that creates more problems than it solves.
