I know several people who have DDI subscriptions and never setup a forum identity to go that way, so I personally would guess at least twice as many as the # listed.
A quick thought before I run home...
But what is the chance that WotC/Hasbro is waiting to make sure that the subscriber count for DDI is somewhat constant/predictable before they start throwing more $$$ at the project(s)?
Pretty high IMO.
It probably is. That's one theory behind the recent print book cancellations and Slavicsek's comment that "we plan to deliver just as much great content for players this year through other formats, including board games, accessories, and digital offerings." They may be diverting this content into the DDI because it's just that much more profitable.I don't get it. If DDI has 100,000+ suscriptions, maybe many more, then it must be the most profitable portion of the D&D section of WotC, right?
I would agree with this and I also suspect that normal practice at WoTC when a publication was near the printing deadline was to ramp up the overtime to get it out. A practice that has proven to be disasterous in the software business but a very easy pattern for developers to fall into.I suspect a lot of the problem is unfamiliarity with software design. WotC has a lot of experience as a book publisher, a fair amount in other forms of physical publishing (magic card, board games), but virtually none in the electronic area. Sure they could hire a contractor to do it, but that went horribly the first time.
