There's a number of us that already started our curating quite actively. But can't say much if there are others though.. Pretty sure @smooth is leading a team out there too (i remember seeing in some chat). We're currently shooting for maximum diversity, and it also happens to be quite time consuming. Glad to also have spot some of your recommendations recently - which means our method is working out. It's a good rant :p there will be a lot to worry about even if Steemit hits 250k people - that'll be a headache. But doing what we can for now to retain users churning out quality content..
