They are established article pages, but my site is under 110 pages and I am always making tweaks. For instance, about a month ago, I discovered and removed some dead links on those pages. Google has yet to deep spider and recache. Beyond things like that, how often should an article page change?
That's a good point about article pages not really changing.
It appears then that Google has just chosen to slow down the cache updates for websites. If you are always making little tweaks, I think the cache updates should be more often and not what you are seeing now.
As you were saying, maybe Google is really focused on rolling out Caffeine and cache updates seem to have taken a little bit of a backseat.
