LinkedIn is a terrible place to get jobs and a terrible place to look for talent. Many people are very unsatisfied with this site for tech/developers. Often one looks great but once started development it is bad. I have not being developing about half of time as the parent thread author. However, all what he said sounds true!!

I never used a site to find work, always through network or colleagues. They tend to know my capabilities best. Head hunters are horrible people for tech. Buzz word and framework doesn't mean a thing. If you a good developer you can figure out how to do anything! It is how you thing and how you understand stuff and how to solve problems that counts.
