One thing that I find strange is that a few of the profiles have full bio's and cv's in place including responsibilities in their current and previous roles. They do however only have 3 or 4 connections. I'd imagine someone who puts so much effort into tailoring their linkedin would have connected to more of their previous and current colleagues.
