avalon VS Patchwork

Sure, https://github.com/dtube/avalon - It's quite possibly the easiest blockchain to understand. The node is written in Javascript and uses a local Mongodb to handle storage of blocks and content data.

i think you added the tittle wrong and also the dtube has been in the steem blockchain but due to the few of the actions cant be handled in the steemit blockhain dtube has moved to avalon which feels choice and to make much more implementable but still people can choice in dtube where they can connect to steemit or hive i they wanted to as dtube allows crossposting

You're effectively describing Scuttlebutt in a nutshell. Small communities that are formed ad-hoc by peering with each other. "Follow" mean you'll help replicate their content for others who follow them + you. Scuttlebutt is already successful even though it's very small so far. Tags and other things can be used to explore content on the network, as long as you've found an entry-point.

I'm a bit split about spreading the word about Scuttlebutt, I don't want to ruin it since it's already so great. But felt it was very related to what you were writing, so here goes nothing :)
