There was a spell that I enjoyed while using Technorati, when I accidentally ran into one avid blogger when searching under "semantic web design." Although the blog entries were irrelevant to the search I did because the blogger wrote nothing about the semantic web, he did have some excellent content on taking advantage of Clickbank to make money. And unlike a lot of web sites, he wasn't selling a jot of the information.
Technorati is relatively easy to use, and its "add to Technorati favorites" button is actually helpful when (if?) you stumble across a blog that you like a lot. It works like a feed reader and can be integrated into the web browser and your web site to allow you to search Technorati's index from both points. To add Technorati to your browser you simply drag and drop hyperlinks (called Bookmarklets) from www.technorati.com/tools/favelets.html. Also the Firefox-based browser Flock has built-in Technorati features; Firefox also has some search plugins.
To add a Technorati Favorites button to your web site, just go to www.technorati.com/account/favbuttons.html, grab a button and link it to your Technorati favorites. Another feature that can be added to your website or blog is Technorati's link count widget, which adds a view of reactions to your post so that your readers can see the comments of other users on other blogs (who are also linking to the comment). You can get this tool at www.technorati.com/tools/linkcount/; you can even add the search engine to your website, and allow your readers to read the blogosphere.
Concluding
It is worthwhile to use blog search engines. Blogs are excellent places for free content (if you can find the right blog). In time Technorati will improve its indexing and also the relevance of its rankings; for now it had better watch the competition and continue to keep the bloggers happy, because the searchers may not be.
