A few new articles are up on DotNetDevs; I contributed to this one about Reflection and the Visitor design pattern. The DotNetDevs site has a high standard for articles, adhering to the quality over quanitity idea. I like it.
On the subject of design patterns, it's been said “Never hire a programmer within 1 year of having read their first design patterns book.” While it's not meant as a real hiring guideline, there is some truth in the observation. The tendency to abuse and over-use patterns once you're first exposed to them is a common side effect; I know I went through my “everything can be solved with patterns” phase.
WeProgram.Net speaker (three sessions now, if you can believe it!) Steve Metsker has written a solid .Net guide to patterns: http://www.awprofessional.com/title/0321126971. It's better than the “other” stuff that is just copied from the Java world (i.e. Metsker took some time and really applied the patterns in C# instead of just changing the source code from Java to C# like “other” books have been known to do).
Happy .Netting!
