Next update: October 2007. In the meantime, look for a M20 badge and more discussion around measurement, influence, attention, and authority. Additions are always welcome - please post links in comments.

Pete, very cool to house the list on its own site. Thanks for putting so much work into creating the M20.

Peter, it would be fantastic to host a conversation among these fine professionals about how they see the role of social media influencing their day to day work. We have a nice variety of businesses represented and I still see articles on blogging written by agencies who advise companies, yet do not have blogs themselves. Or if they do they may not be "getting" what it means to blog.
What does everyone else think?

Peter, I echo C.B.'s comments... thanks for all your efforts! Also, Valeria has a neat idea. All of these marketers you highlight started with a set of business objectives and reasons for doing their blogs. It would be very interesting to compare how it's going with how they expected it would go and how it's impacting their day to day.
In my case, I can't believe the number of contacts I receive each week, via email, phone, and Skype from all parts of the world. In our conservative world of process automation, much of the dialog is off-line instead of via comments. It's slowly beginning to change and I hope this trend continues.
It would be interesting to hear others perspectives as well.

Just stumbled across this, Pete... nice! Looks awesome.

Hi - thanks to everyone for stopping by during the US holiday weekend.
Great idea Valeria - using Toby @ Diva Marketing as an inspiration, it would be natural to profile bloggers here to help build the case for others. I'll come up with a short Q&A and post for answers in the near future.
BTW in case anyone was wondering, M20.com/org/net are all taken.

Wow, love the new features Peter. I'm torn on the flag topic, I'm from England but based in the US :-)
I really like the idea Valeria proposed about finding out more from everyone here on how social-media is used in their work lives. I actually think that it is important perspective to provide, especially for corporations, and people in corporations who want to blog.

Peter - New home, same great list...reminds me of a tagline from a consumer product.
Great to see the list thrive and I am adding M20 to my feeds as well.
