The Alt Search Engines blog is a great place to learn about the huge number of search engines that keep on coming, along with emerging search engine technology.

In my recent post on The Best Search Engines For ESL/EFL Learners — 2008, I neglected to mention that I first heard about many of the sites on that list through Alt Search Engines.

Charles Knight, the blog’s editor, has also been helpful over the past year by periodically emailing me about new search engines that he might not write about, but which he thinks might be helpful to English Language Learners.
