I think people like haejin are clueless about the newsteem. He isn't making a cent for the last one week as all big players are chasing him down. With the amount of SP he has, he can earn good return through curation. And their RCs can be used to claim a lot of account tickets which will be an asset in the future!
I make around 20SP per week for my 5k SP. Curation is now a lucrative business.
