MediaPost reports:

BUZZ-TRACKING FIRM UMBRIA WILL UPGRADE its Buzz Report, which tracks conversations about brands on blogs and message boards, by offering users more refined demographic information and an enhanced method for dealing with blog spam. Buzz Report, which monitors about 11 million blogs and 100,000 public message boards, already analyzes posts to determine writers' genders and ages. The new release will also measure such factors as geographic location, ethnicity, and income level.
