try reading some of the many threads around here about how G is not crawling sites. I've had content up for over 4 weeks thats not even been looked at yet! despite being well linked into the site and having very good one way extremal links pointing to the pages - maybe someone should give G a lesson in building a bot that can crawl!
I read in another thread from someone who thinks Google are covering up a major problem. I'm beginning to think that really is the case. It's been going on for so long now (my site still has thousands of non existant pages showing in the SERPS that are over a year old) yet Google are saying nothing. I find this surprising because there's clearly a major problem with thier systems and they're relying on very old caches as a backup it seems.
I conclude that Google is broken, they're struggling to fix it and they're keeping quiet about it. I also think that their systems are such a hodge podge of patched systems and botched algos that they hardly know where to begin when they need to make changes. I could be wrong of course but I'm sure MSN will be watching this carefully and planning their comeback.
