Real question is, can digital distribution break the stranglehold Diamond has on comics by attracting enough new readers, before that stranglehold becomes a deathgrip that drags them all down.
I think the technology serves as an additional barrier to entry. Beyond that, do digital comics (ones purchased legally, that is) offer some kind of preview mode allowing you to sample more than just the comic's cover?
I love that I can get read comics on my Ipad. But I'm not sure the technology is going to be able to pull in new readers.
And, of course, the technology does nothing to address the issue that comics, as a medium, are not very friendly toward new readers.
