Yay!  Aaron Pettigrew and I have figured out a work-around to get these blogs indexed, and thus findable, by the major blog search engines.  Last week I checked and was dismayed to discover that posts here were not appearing in Technorati, Google Blogsearch, Yahoo Blogsearch or several other key blog search engines.  For some reason the blogging software we are using wasn't "pinging" the search engines to let them know when we had new content posted.    No one knew why this wasn't happening.  It was a problem.

WON'T SOMEBODY PLEASE think of the pings?

These little scribbles of data are the lines that connect the dots in the world of blog-style publishing. Named after an old-school command in UNIX that allows one computer to ask another whether it's alive, pings on the modern Web are a quick way for bloggers to alert the world when they've updated their sites.

Say I post something excellent to my blog, but I don't want to wait for Google to index it or for random geeks to stumble across it. I send a ping alert – a tiny document in a special format – to something called a ping server, which is like a centralized bulletin board that lists every new blog post it's been pinged about.
