Compete.com, one of a number of sites reporting search market share, has released figures for June showing a substantial increase in search share in June for Live Search:
According to a blog on the site, much of this increase is due to the increasing popularity of Live Search Club, a set of games (Chicktionary, anyone?) that use Live Search to help answer questions and win prizes. One commenter on the Compete blog professes to know people who have won 10-20 copies of Windows Vista Ultimate, so somebody's playing, and playing a lot.
Of course there are lots of questions surrounding these latest numbers, and it's almost a requirement to take the numbers from Compete, comScore, Alexa, and Hitwise, analyze them all, and still draw your own conclusions about what the numbers mean.
