These are not bad ideas. I am still learning as a minnow but I am not entirely sure I like the idea that I won't want to vote on my favorite author more than 1-3 times a week when they post every 3 hours. Then again I'm not guaranteed to like everything they post. Then again, that's what curators are for anyways right? To find the quality content, so to stick to just a handful of authors you're not helping with "new quality content". As a minnow and new to steemit I have little argument against the idea, however I do see the positive in it. There have been quite a few posts that I was done with in less than 10 minutes but I was reluctant to upvote when I was done. After 10 minutes I had already moved on and forgot to go back and upvote as the post got buried in the feed. So the 5 minute rule makes more sense to me because yes, I do believe it only takes about 5 minutes before I or any competent reader can decided if they like what they are reading.
