I subscribe to a handful of development blogs, but my most recent and quickly becoming one my most favorite, is Chris Alcock's Reflective Perspective, in which he posts almost daily the 'Morning Brew'. These posts are simply links to other relevant posts on .NET development, as many have attempted before. However, Chris succeeds with this format by consistently providing high-quality, relevant links to stuff I really like to know about. He's on #410 now, which means he's been doing this for over a year, and while I can't vouch for earlier posts, ever since I subscribed I've found him to be a great filter on all of the content out there. Keep up the good work Chris, and everybody else: you must subscribe to this.
