Pick of the week - Panopticon Central
If you are a religious VB.NET developer, you have to mark this as your favorite. Panopticon Central is Paul Vick's blog. Fantastic stuff about VB.NET, code optimization, performance etc. If you are wondering who Paul Vick is, he is the person who has authored the VB.NET language specification and is certainly one of the best authority on the VB.NET language. (I had blogged about this a couple of days back)
