I just want to say that from a newbie's perspective, I do see a lot of improvements. Last fall, I started to look at steemit on the trending page and was turned off by the content, so I did not join. When I looked again this May, I saw much better content and joined. The improvements are there, it's just harder to notice when you look at it everyday.
For my part, I am on Steemit, simply because I enjoy writing; money or no money.
