Too much SEO is what this update is supposedly about.
Confirming, there has definitely been a huge surge in negative SEO. Probably disgruntled people going out of business because they didn't pony up for a real domain portfolio.
politely, you lost me with this statement , can you please expand on it for me.

"older "non seo'd" content is still un-crawled"
sounds like a robot.txt or .htaccess issue ?

"I wonder if some sites with meticulous SEO....... " , i think you are right, everything i am reading is saying google is systematically disliking SEO strategies AND its brain is growing in knowledge rapidly.
I am now getting websites to rank 1,2 or 3 within 5 hours or so simply by blogging about them on MY aged domains ( 10yrs +) google is indexing soething like 1Million domains a SECOND i read, highly active domains like mine must be being indexed every few hours !, not that i did anything to make that happen but it might be my longevity of the sites that is why its happening.
I mentioned this on a different post so i'll keep it short: ACA, "a current affair" did a report against one of my clients business sector ( not them) the next day i created a blog post rebuttal of the broadcast and within 9 hours it ranked 4th , the first 2 were ninemsn dot com dot au and then a competitor that did exactly the same thing as us then our post.......... 9 hours !!!!!
so the moral is, if you have old pages that aren't crawled, there is something going on. Maybe google using a "sunset" system for pages ( for those who don't know sunset means anything prior to a certain date is no longer supported )
