I don't know about polls but I remember somebody talking about social media in general and how to engage with others. I think I saved it somewhere but it had to do with asking questions that trigger others to respond. Not clickbait but just spurring discussion. On facebook there is a group that talks about my hometown. Someone will post a pic of a place that used be but is gone. Or ask a question about some special place they liked and a whole discussion will happen organically. Now if that were to happen on Steemit...
