For a few weeks now there have been various postings concerning the potential use of RSS to replace email newsletter and Chris Pirillo has been at the forefront of that trend. Today he offers the best list of reasons for it to work that I have seen yet.
[Later] Some good points here too, especially the fact that if you miss a number of issues and they are off the feed you’ve lost them unless there is a good archive on the site. Which also reminds me that I archive some lists locally, no way to do that with RSS as easily as with email.
