There are a lot of "delete social media" posts here but LinkedIn usually isn't mentioned by name (unlike Facebook, Twitter, etc).

Some say it's a "must" to have a LinkedIn account these days if one is in a technical or professional career. Others say it's intrusive and not worth it. Some have even said they don't want ex girlfriends or former friends or co workers who fucked them over before knowing where they work.

What's your take on it?
