EXPLAIN LIKE I'M FIVE

I've recently returned to Steemit after a bit of a hiatus, and a few of my Steemian buddies have been talking to me about Busy.

I've requested access and read the front page of the site, but I'm failing to see how it differs all that much from Steemit.

Anyone more qualified able to fill me in?
