Actually, I've always seen Haejin's posts with wary eyes but on the whole found them beneficial.
Even if they were complete TA BS, which they are not, they would still be beneficial for the crypto market and the investors here - but I'm from marketing and see things differently from average people... as this market booms and suffers with the psychology of the people, Haejin is obviously a highly positive element in the game.

The argument abut the steemit rewards is of course a valid one, but an entirely different matter.
