Polling has long been a requested feature on Indie Hackers, and today it's possible! You can add a poll to any new post you create, and logged-in users can vote and/or view the results.
There's more information and an example poll here: https://www.indiehackers.com/post/you-can-now-create-polls-on-indie-hackers-38c3b698af
