Is there a killer app somewhere, I don't think so, it's the conglomerate and metamorphosis of smaller apps that makes a killer app. don't forget the days of 2go to WhatsApp to BBM to telegram and now the whole thing is getting better.
Steemit to me is the killer platform, just an app sir, and no single app can do that, it's the collection of app. For your info @partiko can now message, you can now chat.
Don't forget we are all in this trouble because bitcoin dip not because of steemit. Steem.
Steem On.
