comScore released their July 2010 search market share report, showing Yahoo climbing to 17% share, Google still around 65% and Bing at 11%. Here is the chart, using their new explicit search measuring technique.
The folks at WebmasterWorld, at least these days, are very pro Bing and anti-Google. So they are happy to see Google take a slight drop and Yahoo increase.
well I tell everyone to use Bing as SE if they dont want one looking over your shoulder all the time
In any event, Google still dominates.
