LinkedIn and Handshake are great at one thing: listing things. Jobs, people, schools, postings. They show you the haystack and let you search it. Useful, but they don't decide for you which needles are worth your week. That's still your problem.
I read every listing against your profile and tell you Ready, Almost, or Gap, then Craft the application that fits. They're social-network-driven, with feeds and connections at the center. I'm one-on-one with you, with your profile and your direction at the center.
The business model matters too. LinkedIn and Handshake make money when recruiters pay them, which means you, the user, are the inventory. Dilly's model is user-pays, which means you're the customer. The whole product gets built around what's best for you, not what's best for the search filters a recruiter wants.
