This screen grab was pulled at about 2am EST, meaning the comic had been posted at approximately 1pm EST on Wednesday. That's earlier than a lot of shops have their pull lists sorted for regular customers. I'm sure it was available on Usenet in advance of that.
And these are just people that are dedicated to it as a hobby.
The comic book industry is losing a lot of potential money by continuing to ignore the market for making their books available directly on the internet. Availability online opens you up to customers where there are little-to-no comic books available.
I remember hearing from a Newsarama reader/poster located in Barbados (a lovely country that I'm enjoying some time in at the moment) who indicated he used torrents because it was the only way he could get timely access to comic books (or get them at all). This is purely anecdotal stuff, but I doubt that he's alone or that he represents a small enough group that it should be ignored.
