I've been on steemit for about 45 mins, and about 75% of the content I've browsed has mentioned this guy haejin. Thank you for posting this, as I would love to get some answers, as well. As for the other 25%, this place seems pretty rad. I will say, I was disappointed to get 'excited' about the #spl and then realize it probably won't be around for too much longer like @mrwang mentioned above. That said, I'm excited to get to know the community... some illimunation on the "Steemit Enemy #1" situation would be cool. Cheers!
