Google Provides Tools for Tailor-Made Search Engines
As the headline says, you can create a custom Google search engine by seeding it with a list of preferred URLs. Though as the article says, correctly, "The concept mirrors the approach of a small startup called Rollyo.com." Anyhow, Doug Belshaw has created an Edublog Search Engine using my Bloglines subscriptions as the list of URLs. It seems to me though that Google's technology needs some refining. On Google.com, when I search for 'Downes' I see my site at the top, as it should be. But in the Edublogosphere search we see Downes Wholesale Nursery at the top, which is not only odd, it is not even educational, and almost certainly not linked from any of the edublog sites.
