Not everyone has a linkedin/facebook/twitter account.

True, but most people that would be hired by the startups listed would. No?

Most != everyone

Seriously, requiring sign up via accounts on sites like facebook, linkedin etc is a really stupid idea. Startups (I'm looking at you quora!) need to stop this bullshit.

Edit: Looks like quora now allows email sign ups. Good.
