Here's an interesting interview with a guy hired to write a corporate blog (or weblog). You can read his blog here to see a pretty good example of corporate blogging. Sun COO Jonathan Schwartz also has an opinion. I've noted health care blogs before here and here,
and you can visit some of the best health care blogs via the blogroll
links in the right hand nav bar. Blogging for an FDA regulated company
would be challenging because everything published by the vendor is
considered product labeling and thus subject to FDA regulations; with
the right internal processes I think it could be done.
