The “insert specific tech here” developer: yay or nay?

Published a blog post
Something I've given some though over time, is how developers (and others) put themselves in boxes, presenting as ".NET developer" or "Java architect", and so on.

It's not something I see much discussion about, so it's probably something folks don't care much about, but I do, so just went ahead with writing a post about it  🙂.

Have any thoughts on the topic?
