I would use Busy more, but that interface has issues of its own - mainly, navigation. Steemit and Busy are two peas in a pod. It makes sense that STINC would officially partner with them.
It's sad that there are two "major" sites for Steem...and neither of them are really worth using. Maybe we can just keep hoping for better development?
Better development would make me very happy. People I have encouraged to visit the Steemit.com site are put off by the UI - as for the navigation issues on Busy, I'm glad you mentioned that. I thought it was my ineptitude, lol
The interface of busy.org could do with some changes, but is does feel more stable and nippy, which suggests it is better set up architecturally and code-wise under the hood and could be changed into a better steemit fairly easily, given the right requirements. But maybe that is just wishful thinking.
