I've been working with Dave Broman for many years now on assorted projects and he's just started blogging, opening with a strong article on stackwalking issues when using the Profiling API.

If you're interested in using the profiling API to help you diagnose some of your own performance problems, or just understanding what managed profilers do (and what their strengths and weakness would therefore be) give his blog a visit.  I know he's got a strong lineup of helpful articles coming.

Welcome aboard Dave
