How long have you been around for? I came in at a bad time - right at the top pretty much. Steemit is only a year old so it is still in Beta - there are things with it that could be improved. Steemd is a 'block explorer' for the Steem network and Steemkr seems to just be a Steem frontend/Steemit clone for Korea.
I think this platform, the network it is built on and the tokens that power the network have HUGE potential! We just have to stick it out.
