A friend of mine started a company based around his newsletter turned slashdot-esque news blurb site (ie, what is now called a blog) Techdirt. And, he just got mentioned in this month's CIO magazine. We used his services at Neotonic (and I can even tell you his enterprise blog software uses ClearSilver), and its a very useful way to keep abreast of your industry. Check out the Wireless site for an industry wide example.
