The flip-side of blog-writing is blog-reading (and I'm a voracious reader, even though that means skimming and frankly ignoring a lot). Ray says he reads employee blogs, inter alia, to inject some serendipity into the Overhead's perspective.

Well, we all need that. It works not only 'vertically' (after all, hierarchy is designed to filter communication, and it works all too well), but also horizontally - between departments, across workgroups, connecting individuals. If everyone in the company had a true workblog (and I will, as will you), the network of subscriptions would "pave the beaten trail".
