One more note of Google strangeness before I call it a day.
I've heard of people talking about the cached/preview page being different than the title/snippet meaning the cache/preview is out of date, but I'm seeing really odd stuff when I compare the preview with the title/snippet and even the preview page template to the one that should be in place.
Some examples are:
Result title from two weeks ago with the snippet from two weeks ago and the breadcrumb under the result from two weeks ago, but the preview is showing the most recent version of the page. (So title, snippet, breadcrumb are two weeks out of date but the cache/preview isn't.)
Then there are some that are the other way, with the result title, snippet and bread crumb being the newest version and the cache being two (or more) weeks out of date.
Then there's one where the title, snippet and bread crumb are from the most recent version of the page, but the preview page is over 5 weeks out of date.
Then there's one where the result title, snippet and bread crumb are the most recent. The information on the page in the preview is from the most recent version, but somehow the template of the page is 5 weeks out of date. (So, the result title is from within the last two weeks, the snippet is from within the last two weeks, the bread crumb is from within the last two weeks, the content of the page in the preview is even from within the last two weeks, but the template of the page in the preview (with the current information on it) hasn't been on the site for five weeks, meaning so somehow they're wrapping the new page information that was only available about 2 weeks ago in an old template. HUH?)
