(Author's note: Circa 2005)
Media Orchard stumbled upon an interesting site called Top 10 Sources, which ranks and publishes what it considers the top newsfeeds in various categories.
Here's the site's Top 10 in the "media" category:
New Media Musings
Joi Ito's Moblog
Romenesko
E-Media Tidbits
Micro Persuasion
BuzzMachine
CyberJournalist.net
I Want Media
The New York Times
paidContent.org
(Media Orchard would like to point out that we do occasionally publish rankings that don't actually include Media Orchard. But we're bitter about it.)
