@Sgt_Kickaxe - is yours a crowded space?
I'd have to say it's not a hugely crowded space, it is however filled with knowledgeable visitors looking to further their hobby. In this space a content farm type of site stands little chance of lasting very long because it's fairly easy to tell when an author isn't 100% knowledgeable on the subject. That limits the number of competitors quite a bit.
I've gone ahead and trimmed the remaining 10% of my ignored(by Google) articles by removing them from Google but leaving them intact. I'll work on those pages and allow Google access to them again one at a time, as I can, but not before I wait a good three months to see if the other pages improve.
If you've done this before how did it go?
