The problem is ... should every one of WotC:s customers come first?
Given that there are many periodicals (The Sun, The Economist, The NY Times, The NO Times-Picayune, and the entire Guitar Player/Bass Player stable of magazines, to name but a few) that have both a print form and an online form, it is quite probable that every one of WotC's customers
could have come first.
WotC had a chance to have a Win-Win situation and blew it.
What to support, and what not to support?
You support what works. You support what your customers view as a significant reason for giving you their money.
Personally, I think WotC is overestimating the popularity of e-zines. My personal experience with the 2 mags is that usually, one person in the group buys the magazine, and everyone else borrows it. While not impossible, it's a bit more difficult to do that with an e-zine.
(And, for the record, I'm no technophobe- I've been mixing computers & gaming since the mid-80s. I have always gone back to non-electronic gaming supplies & techniques. They're a supplement, not a replacement)
While Pyramid is cited as an exemplar of the shift from print to e-publishing, even that decision cost them readers. Myself, for instance.
