If you're only referring to what recruiters send to you, then you're frustration is for not. While I can understand your issues with labels, this is a keyword driven era where you have to summarize your entire skill set into a few short keywords so people can categorize you.

While recruiters tend to generalize requirements, they aren't looking for generalists. They're looking for candidates that match specific keywords.

I get letters from them for Drupal contracts, when the C# to Drupal ratio is 500:1 on my resume.

Unfortunately, the tech world has made us "our f-ing khakis".
