Hello Jerry, Thanks for writing this post. I hope that you received my message on Steemit Wallet. I used Steemkr.com yesterday when Steemit.com was down. I do have eSteem app installed on my iPhone which makes it very easy to use Steemit on the go.
Busy.org has the easy interface for people who are comfortable with terminology like Like, Comment or Reblog instead of upvote, reply or resteem. We use Reply for comment and both replies on the comment, but on busy.org they use comment and reply(reply is for replying to the comment. I have written a post how I was using steemkr.com and translated the Korean language to English. It has the same interface as the Steemit.com. The only difference is the language which you can easily translate using the Chrome built-in translator. If anyone here wants to check out the article that I wrote then here it is.

I did not know about beta.chainbb.com, so thanks for that info.
