I have found a number of online newsletters and publications about teaching with technology that are worth scanning, if not reading. Many of these are available as RSS feeds so they can be seen here (see below) or brought into your own RSS reader.
There are also books -- remember those print items?
And now having found a number of really interesting podcasts, mostly about writing in general, although I know there are a lot of blogs devoted to teaching with technology that are providing commentary as podcasts. I've begun an annotated list of podcasts.
