this website has loyal following where people post thousands of pages of new content daily...

Google has recently acknowledged that it's been having a problem which is now being fixed. A link to the Google statement by JohnMu was posted in the current update thread, but I'll make a note of it here as well. The problem appears to be affecting many sites that update frequently...

Google appears to have stopped indexing blogspot.com
[google.com...]

I just wanted to provide a short update. This issue should be resolved soon, but it will take a several days for everything to catch up and for these changes to be visible. I'll provide another update after the weekend. In the meantime, there's no need to make any changes on your side. Content from your sites will continue to be indexed during this time (though perhaps at the moment not as quickly as before in some cases). Thank you for your patience and for all the feedback!

This is on a Google support thread discussing blog links not getting indexed. It may or may not also relate to other types of indexing issues some are observing.
