First I don't consider Dragon or Dungeon a real digital magazine in their present state. If there is a ton of free stuff on thier site why pay to read the few articles that are not free? What is so much better about these articles then the free ones? Are any of those payed articles written by gamers who don't work for Wotc? What exactly are you paying for with a subscription ?
Of course, at this point you're changing the argument - your original criticism was that too much content on their website was going behind the paywal. Now you are arguing that there aren't enough DDI articles. You can't really have it both ways.
I suppose that is my main objection here - you've made a number of claims about the site, but I'm not sure any of them really accurately reflect the state of it. I'm not sure if you are basing your claims off of past experience with the site, or just what you've heard through the grapeline, or what.
That said - right now, yeah, the magazines are having some serious issues. Keep in mind, though, that this is only over the last 2-3 months. Prior to that we had plenty of free content as well as plenty of subscriber content.
And we did see many excellent articles. Usually offering new content - the free articles we are seeing these days give DMing advice, news about the game and gaming community, answer questions and provide feedback, and preview new material. The subscriber articles would give new character options, new monsters and magic items, and other direct material for the game.
I'd say that there is room for both, and that the division is a good one. As for who is writing the articles - there are plenty of freelancers who have shown up in the online magazines. We do certainly see many of the same names again and again, but I believe we also see others who have no direct affiliation with WotC.
And the free articles often feature similar 'gamer for gamer' content, as with the current D&D Kids series.
Now, again - right now, the magazines are definitely having some serious issues, and I honestly have no real idea what is going on. But this month is by far the exception rather than the norm - since release, they had over 2 1/2 years as effective and high quality digital magazines that were well worth the cost of subscription.
And even now, with issues for the DDI magazines themselves, the free content on the site remains substantial and useful, and certainly puts to the lie your original claim that nearly everything on the site was locked behind the paywall.
