Well, looks like my idea for a Delicious Library-style comic book database app is all for naught. From the DrunkenBlog interview with Delicious Monster co-founder Wil Shipley:
I knew it’d work from the beginning, actually. The actual credit for the real-world metaphor in Delicious Library is a bit lost in the mists of my brain, but my recollection is that Mike always wanted to do full-size, beautiful covers, and one day I said, “Hey, look, let’s draw them the correct sizes and aspect ratios and put shines on them and put them on shelves.”
And Mike said (as he always did), “Yah, I thought of that last week, but I decided against it”, and I said (as I always did), “Well, I think it’ll be totally cool and compelling and we should do it and blah blah blah (half hour passes) and then when we eventually do comics we can blah blah… (more time)” and so Mike started mocking it up and his first mock-ups were horrible but we instantly knew we were doing the right thing.
Emphasis mine. Shipley, you magnificent bastard!
