Okay, I've been neglecting the M20 for a variety of reasons - but have still been mulling ideas about where it should go. I'm thinking the best option is a wiki where marketers can add and edit their own information. So in the near future, I'll redirect this domain over to http://marketer20.pbwiki.com/ while the information here will live on at http://blog.marketer20.com.
Thoughts? Thanks for your support.
