Questions

It is my understanding that comments do not affect curation of the parent post. In reality, comments are separate posts in themselves and get author rewards and curation values just like top-level blog posts.

I thought I had heard mention of some effect when the person that upvotes does or doesn't leave a comment.

But I knew about the posts and comments both being posts with their own curation.

I do know it is generally frowned upon to upvote your own comment without upvoting the post itself, but I don’t think that affects curation.

Oh, hah, such behavior hadn't even occurred to me.

A side note: I found a new steem app; musing.io. This is an appropriate place to ask all sorts of questions, probably even steemit ones. Cheers!
