And now for something completely different.

WoWinsider has a post about Burning Crusade now being offered as a digital download, and they wonder why Blizzard didn't do it when it was first released.

Offering direct download at launch might irritate retailers.
Offering it now might get a few people to buy who weren't motivated enough to go out to the store.
It probably costs them relatively little to do this.

And they miss the most obvious reason why.

Because they didn't want the servers to be hammared by 2.4 million people trying to pull down a 2 gig download all at once.
