I do think that people with less than a certain amount of steempower should be limited in how many posts they can make per day. That would encourage them to invest and post more and help steemit financially or to post more meaningful things and help add value to the community. Memes and jokes are great but when you compare that with a well thought out heart felt post there is not a whole lot of value added in the latter in my opinion. But what's great about steemit is that if someone disagrees with me they have the power to reward any content they find interesting or entertaining.
