PBS today launched a new blog that claims they are. MediaShift, written by Mark Glaser, promises to
"track how digital media technologies and techniques such as weblogs, RSS, podcasting, citizen journalism, wikis, news aggregators and video repositories are changing our world. It will tell stories of how the shifting media landscape is changing the way we get our news and information, while also providing a place for public participation and feedback."
If anyone will have intelligent ideas about this stuff, that person seems to be Glaser. He wrote a weekly column for USC Annenberg School of Communication's (Online Journalism Review) and currently writes the OPA Intelligence Report email newsletter for the Online Publishers Association.
I'm looking forward to learning more.
