Smart and inevitable, to secure dominance in the talent vertical. I remember walking into an org where none of the engineers or UX folks had Linkedin accounts. They didn't need it to land in a healthy workplace w/ a decent salary. They were active on GitHub instead, had Angellist profiles. One of them mentioned LI's InMail tool drove him away. Another said he can network just fine with Meetup and twitter.

Edited those typos.
