I would definitely say this is one adorable thing I know you always do and it is really commendable; engaging your commenters. You always reply every single one of them.

I recently found out about the pinned questions. It was a new thing for me as I didn't notice at first but started noticing it. I think that is a great idea as it gives people direction on what to even comment on, IF they don't initially want to comment.

If you're pinning this comment asking them to vote, be sure to also ask them in the video itself.

I like the reiterating aspect of it.

Anything that gets the viewers to have a day or give a comment should be employed, either the pinned question or having something to be corrected about.

Gracias amigos hahaha
