And I had a Linked In profile. Despite developing a quite absurd level of expertise in my field I think I had one approach from a recruiter via Linked Ln who wanted to know if I could do Photoshop ("designer" ambiguity at work) in the four years I was there.
What this means is that no matter how you dress up your skills and aspirations it’s your job title that hooks them in. Simple SEO works wonders. Recruiters are busy people and Linked In search is a blunt instrument. This also suggests two ways of gaming the system.
One is that you should massage your Linked In job title to match the job you want, not the one you have. The other is that if you're an employer and you want to keep your ninja/rockstar devs you should contractually oblige them to refer to themselves as PL/1 programmers or Mainframe Tape Operators.
