As I was lying on the couch reading The Boston Sunday Globe I came across an article by Penelope Trunk in the jobs section: Blogging Offers a Lift to Your Career.
"Blogging allows you to create a high-quality network for yourself based, not on the old model of passing out business cards, but on a new model of passing out ideas."
"Most of the time you spend blogging will be reading other peoples' blogs and linking to them and writing commentary on your own blog about what others in the blogosphere are talking about. It's a constant course in your specialty and keeps you on the cutting edge."
I think these are two great reasons to blog in the blogosphere, as well as within the enterprise.
