I still don't understand it completely, but I am glad that their has been some progress made by the folks at Steemit.com, Inc.

Personally, I prefer the Tribes made on the Engine side-chain. As well I am a great fan of @steempeak. Both have done a wonderful job and make navigating STEEM much easier for me. As both the Communities feature of Steem and the SCOT tribes with coexist and are not competitive(?), there are the choices of using one or the other, or both.

I look forward to seeing the developments in the future.
