Google relaunches its blog-search site. A good, broad-based site of this nature would be valuable to businesses looking to tap into the zeitgeist, eavesdrop on the vox populi, or, y'know, just find out what people are saying about them.

Blog search needs a refresher. Pioneering firm Technorati seems to have stalled some time ago, and other sites -- including Google -- have not taken the world by storm. Niche sites and memetrackers have their place, but there is power in the ability to follow a brand or product across a wide spectrum of blogs.

RWW worries about the impact on TechMeme, which the new site resembles, and wonders if Google will be fast enough to engage news-hungry tech bloggers.
