Adam is the moderator of 4 Internet discussion groups and newsletters. John Audette, President of MMG, moderates 2 highly subscribed lists. Meanwhile, MMG puts out several other web based resources helpful to the Internet community. As a side effect of their lists and on-line resources, MMG has developed a series of marketing vehicles that create business for them. In addition to participating in discussion lists and receiving newsletters, you may want to think about starting a newsletter or discussion list of your own.
Implementation is fairly simple and inexpensive.
The real investment is the time to do it right. Moderating a list takes a tremendous amount of time and effort. Boettiger and Audette spend between 1-2 hours daily maintaining their lists. Weeklies and monthlies are obviously easier to maintain. An example from MMG illustrates this point.
