LinkedIn – Good or Bad?

This takes away the power that LinkedIn provides and defeats its entire purpose. LinkedIn isn't a network to meet your next potential friend - it's to engage with others in your industry and openly share your network in a semi-private manner. When I'm looking for a job, it's beneficial if the hiring person is just a 2nd connection away because then you can send them a PM. Send a short, friendly message and you're increasing your chance to be noticed.

If they don't respond, or accept your connection request, whatever - nothing personal.
