"There are some areas that are called "sticky segments" but I don't know much about them."
This is the particular information that I would like to read about.
I have read Blaine's blog and thought it was right on target with both the enthusiasm and the concerns. Thank you for suggesting it.
There are some things that I think need clarifying or where I want to go a bit deeper on a topic. And sometimes there is conflicting information so I like to follow up (I don't mean Blaine).
Sometimes the time issue has been written about in a way that suggests we shouldn't expect anything more recent. jbarry gave an example of something that is not thousands of years back but was a very reasonable example. I thought he might have more of a handle on the timing issue and he did.
