The Entangled in WWW blog has posted a smart idea for taking full advantage of Gmails labeling system and RSS/Atom feeds.
There are many emails which I passively consume: newsletters, job vacancies, forums, mailing lists (on which I lurk), banking alerts, blog comments, bug tracking, and so on. These emails may require action, but the action does not (usually) involve replying to the sender.It seemed to me that these emails make more sense as feeds, and it would be better to review them in my feed reader instead of having them clog up my email client. Essentially, I wanted to restrict email to non-passive, two-way communication, and I wanted to utilise RSS/Atom for content consumption and service monitoring.
His solution is to setup Gmail labels and subscribe to that labels feed (e.g., https://mail.google.com/mail/feed/atom/label/) from a feed reader that supports authentication. This is a really cool idea for keeping up with your no-reply-necessary email.
