As people who read this site know, i have a penchant for Microsoft schadenfreude. I savor it, and then spit it into a bucket.
This one tasted pretty good (via TechConnect):

According to the data gathered by web analytics firm StatCounter, Microsoft’s decision engine, Bing, has seen its US search market share decline for the first time in September. Launched in June, Bing has gained market share in the summer months and topped 9.64% in August but as autumn rolled in, in September, it lost more than 1% and settled at 8.51%.

Talk about fizzling out quickly.
