I have not heard this theory before. I haven't noticed any degradation in
terms of search results either. Suggesting that Google have fallen behind is
something that would make big headlines (same with studies that argue Google
lost a top position), so it's probably just wishful thinking. In operation,
I am sure that they take into consideration all such risks and replicate the
data as required. Even "Big Daddy" seems to have been corrected/re-aligned.

Yes, that's true.

They should probably aim for a niche if they haven't the required capacity.

Yesterday I discovered that MSN put my at number 5 for 'othello'. That should
be a real embarrassment for them. I wasn't bombing that site _at all_. It
must have been their fluke, or else their algorithms remain as terrible as
ever. But then again, what else is new? *smile*

Shields up? I am not sure about exclusions. However, it is good to keep an
eye on the logs/stats. Some ratbots can crawl an entire site within hours,
depending on its size and available bandwidth. This slows down real
visitors, crawlers and it can cost you money, as well.
