Normally, I don't do a lot of link exchanging or guest posting here because most of the entreaties are marginally relevant.
However, Nicole White did outpoint her Online College site, and I think it's worth taking a look at. She recently posted "Skip Journalism School: 50 Free Open Courses."
Not that I recommend skipping j-school mind you (ha!), but whether you are in school or in the field and wanting to brush up, there are some good links here. Many are from the MIT open course site. You can pooh-pooh that if you want, but remember, MIT's advanced communications lab has been on the forefront of a lot of the developments now roiling your media life.
