It seems there will be no shortage of search engines that scour just the blogosphere. A new one launched today, called (out of a desire to be plainly descriptive or a lack of creativity) Blog Search Engine. From Loren Baker of Search Engine Journal, the utility produces results based first on time and date, then on key words. The engine updates minute by minute, “spidering and trolling RSS feeds and syndication sites,” according to a Search Engine Journal announcement.  You can choose to search blogs or moblogs.
