Watching my referers, I suspect someon of doing some fairly deep analysis of the spidering and indexing patterns of
various search engines. How else could you explain referers like http://search.msn.com/results.aspx?ps=ba%3d(0.15)0(.)0…….%26co%3d(0.15)4(0.1)3.200.2.5.10.1.3.%26isURL%3d1%26aq%3dwww%2bbug%2bgoogle%26pn%3d1%26rd%3d0%26&q=www.bug.google&ck_sc=1&ck_af=0
and http://search.msn.com/results.aspx?q=w.w.w.google.ro.&FORM=SMCRB.

I don't have any real idea what these people are hoping to achieve. I'd speculate they are testing the popularity of
various words so they can possibly game systems like adwords, or maybe to register domain names for popular word combinations.

Anyhow, it's very weird, and I'm interested in any further informed speculation.
