The changes I've noticed are that hubs are not featured unless they are up to par. So Google does not get them.
So it's an in-house thing--this writing whatever comes to mind in an anecdotal fashion about your own life. It doesn't go out to the rest of the world, I assume. (yes/no?)
I'd say that all hubs that are not up to featured standards probably should not be available. Yet, writers starting out would not be able to learn from their mistakes.
People have to take note of the number of check offs that a hub lights up in the right hand top corner of their blog as they are making a final review. If you don't meet those check offs, don't publish it!
AND WRITERS NEED TO COMPOSE ON MS WORD (or another word processing program) AND THEN TRANSFER IT. WRITING ONE'S CHAIN OF THOUGH GOES NOWHERE.
