Comixology's purchase and the adjustment of its iOS app

Hey guys, smarter people than I are talking about this a lot this week in the wake of a big ol' change in the way Comixology (now owned by Amazon) functions through its iOS app. Lots of the functionality changed (or was simply removed) and it made it harder for new fans (well, for everyone really but diehard fans will likely adjust if that's where they read their comics) to really break in. I bring it up only because Mark Waid had a really interesting article on his blog about it and I think it's worth checking out. Click on that link if this sort of thing (or Waid's smart writing) appeals to you.
