I've joined, I've verified I've blogged, I've upvoted and I've commented. Mostly I have read - A LOT. And have discovered much, but there are still a few things I don't understand.

Is there a limit to posts per day, and does that limit include comments as well as blogs.

Is there a limit to the amount of posts you upvote? From how I understand it, it is better to upvote a post from a popular blogger earlier?

Can I still upvote a post after 12 hours, just because I would like the blogger to know that I have read and appreciated their work, even though the upvote would have no value?

Lastly (for now), once or twice I have upvoted a post and seen the earnings for that post go down, why is that?

I read an article that Steemit is growing exponentially at the moment and I'm sure many the new users would love to have more information, as this can be a slightly more technical platform. Well, especially for those of us who are not technical at all!
