I traded e-mails the other day with a supplier to the communications field who commented that he has seen tons of public relations and external communications weblogs, but not much aimed at internal communications.
My first stop in search of blogs on the subject of employee communications was Constantin Basturea's Bloglines PR List, but there doesn't seem to be a category for that kind of blog.
Off hand I can think of a few that profess to cover internal communications, but none do so exclusively:
Additions, including several specific to internal comms.:
A Technorati search for "employee communications" didn't turn up much. One blog, Welcome to the ICA, was launched in the last week, and cites the person who asked me the question about internal communications blogs (so I'm thinking he may already know about that one).
The NewPRWiki has a page of links about internal blogging, but it's more postings about blogs for internal communications, rather than about internal communications itself.
If you have others to add to the list, please add the URL in the Comments, or send me an e-mail: eggertson at gmail dot com.
Thanks for your help!
Update: I've added three more blogs, thanks to Constantin Basturea and Andrea B (I wasn't sure if she wanted her name used, so I'll leave out her last name). I''ll add more as they come in.
