A survey from Stack Overflow says that 20% of those surveyed (those on Stack Overflow) do not have a LinkedIn profile.
Like with all surveys (I say this every time I post something like this) the “who was surveyed” matters. Maybe the IT pros on Stack Overflow are less likely by nature to also be on LinkedIn?
I don’t want to get lost in that part although I was surprised given what I hear at tech groups and meetups in Minneapolis the number is not higher. Yes, I said higher.
