It was a nice small read but just like you said there is nothing new about RED in it, this kind of articles are nice to read for the ones who are new to this project and they want a fast way to find out something about this project. It's nice to post it here because here will be saw by the newcomers who are skipping all the other pages in the thread.
You are right with the newcomers part, I think there will be a lot of newcomers with the air-drop program that is going on right now and it is good for them to have what to read about this project to get familiarized with it.
