From Eric Peterson at JupiterResearch:

I'm not sure if anyone noticed but the long-awaited announcement that CheetahMail has acquired Harvest Solutions came today, continuing the trend of small analytics companies looking for a new sense of purpose or focus in life. Ironically, when we covered the analytics vendor landscape last October (requires client login), Harvest Solutions was in a tight cluster with Fireclick (acquired by Digital River), Urchin (acquired by Google) and DoubleClick (discontinued support for SiteAdvance, partnering with Omniture instead).
