Greg Linden reports that Steve Rubel and speculate that Yahoo is building a weblog search similar to Technorati and Feedster after seeing evidence of a new Yahoo RSS crawler.

This new crawler is called Yahoo-NewsCrawler Test.

In my opinion, Yahoo! is the search engine which is the most interested by RSS technologies, followed by MSN and Google. Google seems to be late on this point - unless it is also building its own blog search engine or preparing to buy a leading blog-related company?
