Teleread: E-book market is a complicated mess

Chris Meadows at Book Business' sister site Teleread writes today:

At GigaOm, Matthew Ingram writes that our relationship with e-books is “too complicated.” He cites the example of some innovative new e-book-related social-networking services, OpenMargin and Readmill, which can only work with DRM-free e-books—meaning they will not work with most of what Amazon and Barnes & Noble sell.

The ability to “share” e-books with friends is not uniformly available, either, often locked down by publishers who want people to buy their own copies.
