Evan Schnittman‘s publishing blog Black Plastic Glasses is ending. The blog had been dedicated to digital publishing and eBooks, and Schnittman feels digital has become a mainstream part of publishing.

He explained in his closing post: “We no longer have the luxury of openly discussing the issues at hand, because all of the issues make up the cornerstones of how we do business. Publishing is digital and everything we do is based on digital. Any real discussion of how we approach the business is a discussion about core strategy… and that discussion is usually, if not always, a private, severely limited-audience kind of discussion.”

Schnittman closed the blog with a new pair of glasses, as seen in the photo on the right. He wrote: “Today I move begin the process of building a new brand. I close out this blog not with a word, but an image. Digital and I have both gone mainstream.
