I was reading some very good posts on WhatsNextBlog, whose B.L. Ochman I’ve interviewed last month at SESNY06. Most of the bloggers are using a variation of the same technique, including Doc Searls (I’m a subscriber to his RSS Feed).
Essentially, the technique is to subscribe to as many RSS Feeds as you can stomach and read (one’s you like). Bloggers use RSS and email along with PubSub and Technorati Alerts ……a lot of leg work. But that’s what you have to do to get content - otherwise it’s hard to know about all the stuff that’s going on.
