MCSD ?
I am pretty old for this profession - I laugh (sadly) when I read about others turning 40. I've been doing that for more years that I want to remember.
I have my DosEquis learning project to force me to learn more .NET that just the VS.NET way and this is working.
I also need to focus on things that the "young" guys aren't interested in. My previous work has usually been hardware/embedded and embedded mixed with windows servers.
At work, I am the build master, configuration and deployment person. I have written a lot of tools to support this. Also I have been the general purpose solver of a lot of technical problems with our product. Learned a lot and I don't think that there that there was a lot of interest in what I was doing as long as it works.
Anyway, I need to find more ways to stand apart from kids. Luckily I get interested in most everything.
I have an MCSE, which was useful at a previous company, and am thinking about MCSD, whether it would be useful or not. Wouldn't or shouldn't hurt.
