Steemit, busy, chainbb, and a few others are all interfaces to the blog chain. They all work a bit different. i.e. on busy.org, I can save a post as a draft and publish later. also, when I put busy as a tag, i will get an upvote. On the other hand, I am having a hard time to answer replies from there since they are all mixed into an activity tab and you have to find them between upvotes and resteem notifications. Also, I haven't figured the wallet out on busy.org. I am going to start using chainbb for the forums. But they take 15% of your earnings. And I don't have much of that :( . We shall see which one turns out the easiest in the end. Right now, they all are good, but not really great :)
