Probably that's how "there is huge programmers shortage!" myth starts. I don't use LinkedIn and will never use it as any other products that rely on dark patterns and disrespect for privacy. Problems with OSS I've written in my other comment. And I'm really not in minority -- most of very good programmers I know are like this. So sorry, but as a requiter you are only doing disfavor for yourself relying on minor pool of candidates.
