Philipp Lenssen always finds great stuff at Google. The latest thing he found was that a search done on _,.-~*'`'*~-.,_ brings back only Oriental results in Google. He asks why in his forum thread. One individual notes that a search on just _*_ brings back very similar results. Andreas said; "_*_ is sufficient � Google recognizes only underscores and wildcards."
Interesting to note that Yahoo, MSN Beta and Teoma all bring back zero results for _,.-~*'`'*~-.,_.
