The blogosphere is a wide and ever expanding territory. With more than 70 million blogs, certainly there needs to be a new and effective way to perform searches on these territories than using conventional search engine. Thus the blog search engine & social networking sites for blog posts were born.

This little application originates as the brainchild of David Sifry when he placed a hack on the Penguin Computing Linux box to research blogs for the Linux Journal publication. The serendipitous invention was called Technorati and today, Technorati is the no #1 Blog Search engine in the world, with over 80 million page views each day.

More Blog Search Inventions

Following the birth of Technorati, more blog search applications were introduced into the market. Feedster, BlogPulse and Live Search are just one of the many names to grace the world of blogosphere. All these new blog search engines have similar features which are different than the workings of the algorithms of the normal search engines.

Differences between Blog search and Search Engines

The difference between the blog search engines and the common search engines are, blog search only searches the blogosphere and displays results derived from those pages. The results are usually displays in reverse chronological order, with the latest on top of the older posts. One more important feature of blog search is that they are tagged and indexed via syndication. Syndication basically means they are updated and informed via RSS feeds, and as soon as a new post is made and pinged. The blog search will index those syndicated pages, instead of waiting for the spider programs to crawl and index them during periodic intervals in the normal search engine. This makes tagging an integral part of your blogging effort.

If you have your own blog, you can benefit wholly from those blog search innovations by pinging after every single post and adding appropriate tags to them so that they can be picked up by blog search engines and added to those search results whenever a keyword using those tags are used.

PostOnFire is a social network site for bloggers and blog readers to submit & discover new blog posts.
