Public libraries, much like the Post Office, are beset by questions like "Does anyone use that?", "Isn't print dead?" and "Doesn't private for-profit enterprise do everything better?" And while those are all good test questions with intricate answers, the askers tend to get self-satisfied and leave the room before anyone else even starts to answer.
There are also stretches - without any NGOs or foundations to help run a libraray. This seems especially true in the red states, which are also of course the places most resistant to taxation for public projects.
Which is to say that Mellow Pages seems like a great idea. I mean, it's cool in New York, but it may well turn out to be necessary in other places.
Like the name, too. Has a certain Zap Comix air.
