Exactly! The change on Tuesday will hopefully increase the quality of posts.
Issue #176

Each root level comment has a reward weight which impacts the end payout of the post. We are targeting 4 posts in 24 hours. Your first 4 posts in 24 hours will not be penalized. After that, they weight is decreased from 100% based on your average posting frequency. Having a frequency just barely higher than 1 every 6 hours will have very little impact, while spamming will be penalized heavily. This change is aimed to increase the quality of content at the cost of quantity.

The developers realize if people can post as often as the like, then steemit will the filled with throwaway content. Yes there are some funny memes and interesting links to YouTube articles, but if you have four posts that earn 100 percent, most people should focus on creating the most engaging content that is unique to them and cannot easily be copied. If the value of the content isn't inspiring or entertaining, steemit would become a less interesting place. Comments are not limited so engaging there will be important too.
