Blog Search Engines

Out of curiosity I read about "Blogs" on Wikipedia and selected a Blog search engine. I then attempted to find my recent Blog entry "Map and Compass Training." I chose the search engine Technorati and located my Blog entry on the first page.

I was stunned that Technorati had a catalog for over 55 million Blogs. I entered the key words "Job Corps" and was dismayed as some of the entries. I need to read about Internet security. I understand how easy it is for those intent on doing harm to children to use the information on Blogs. This was a good exercise. Is "Blog" capitalized?
