Here's the bargraph which was missing in the last post. You see the number of pages found by google and by altavista depending on the number of 'o's in the search phrase "sooo bored". I had to plot this in log scale, so a difference in the height of the bars by only one line means that the higher one is ten times the lower one.

I can understand that when writing more than one 'o' you do not stop with two, but why do people avoid six 'o's, except for when they are spidered by altavista?
Also ratio between the number of pages found by the two engines gets smaller for seven and more. Could it be that google boosts such pages?
