My inbox a good place for me to learn about the existence of a new issue of something, but a poor place to actually read said issues, to keep track of what I've read, and manage a 'library'. I want e-reader-like features: - save my place - highlighting - annotations Should these features be added to Gmail? I trow not. Better to have these newsletter issues converted to some appropriate format and sent to my library, along with my ebooks and saved web pages.
