Barry Ritholtz is very impressed by Google Weblog Search http://search.blogger.com/:
The Big Picture: Game Over in the Blog Search Space: Today, Google introduces Blog Search.... Google reminds everyone why they are such a fabulous technology company -- more than their sparse and clean interface, their products simply work better than everyone else's -- and often by orders of magnitude. My first try with BlogSearch revealed 613 links in 0.08 seconds, some as recent as 37 minutes old. Competitors typically lag by days and sometimes weeks.
Its game over in the blog search space.... It's also a fascinating reminder how fast and comptitive the technology space is; While Technorati http://www.technorati.org (probably should) get credit for identifying the blog search space, they moved way too slow to get their product offering up to speed.... Meanwhile, this is yet another reminder of why Google is the most important Internet company out there (not neccessarily stock, but company).
Now you understand why Gates and Ballmer are afraid of them. They damned well should be. Google keeps raising the bar . . .
Blog Search is Google search technology focused on blogs. Google is a strong believer in the self-publishing phenomenon represented by blogging, and we hope Blog Search will help our users to explore the blogging universe more effectively, and perhaps inspire many to join the revolution themselves. Whether you're looking for Harry Potter reviews, political commentary, summer salad recipes or anything else, Blog Search enables you to find out what people are saying on any subject of your choice. Your results include all blogs, not just those published through Blogger; our blog index is continually updated, so you'll always get the most accurate and up-to-date results; and you can search not just for blogs written in English, but in French, Italian, German, Spanish, Chinese, Korean, Japanese, Brazilian Portuguese and other languages as well.
How do I find Blog Search? There are a few different ways you can get to Blog Search: blogsearch.google.com (Google-style interface), search.blogger.com (Blogger-style interface), The Blogger Dashboard, The Navbar on any Blog*Spot blog. It's the same search in each place, no matter how you get to it. The Navbar, however, provides two buttons: one to search the blog you are currently viewing, and one to search all blogs.
How do I use Blog Search? Just type the word(s) you want to search for in the text box and click "Search." That's all there is to it! If you want more control over your search, click the "Advanced Search" link to the right of the search button. There you'll find options to specify titles, authors, languages and more. Once you get your search results, there will be an additional link that allows you to switch between displaying the results with either the most relevant or recent results at the top. In the Blogger version of the interface, there is an extra "use search options" link beneath the search box. This will show a few of the most common advanced options, such as a specific blog or a date range to search within.
Which blogs are included in Blog Search? The goal of Blog Search is to include every blog that publishes a site feed (either RSS or Atom). It is not restricted to Blogger blogs, or blogs from any other service...
