I think SteemCommunity would be a good witness, but I am somewhat biased in this opinion. @abh12345 and @paulag both run curation leagues, and I participate in Asher's curation league. They are both about driving the engagement levels up in steemit. They keep tack and pull records and let those who participate know how well they are doing in engagement with the community. Asher pulls a lot of data, and has a lot of data post. Through some of his post and data pulls you can see where the "action" on steemit is.
I just wanted to echo agreement. I just started the engagement league, those data sheets are a gold mine of info. Those two seem to go out of their way to help out little fish. There also seems to be a strong focus on the long term health of the platform.
