Gone are the days when word of mouth was the way to get referred. You don’t need to actually know somebody who’s in a company – with LinkedIn, you establish professional relationships without breaking a sweat.

Picking up from the massively successful phenomenon of social networking, LinkedIn can be called professional networking – instead of establishing a social / friend network, you build up a web of professional contacts. You can reconnect with former colleagues – which just might be the thing you need to make some extra cash from part-time, full time, or contractual and / or project-based work. The physics are the same, but the aim is different. LinkedIn also features a referral system, where satisfied employers or well-known colleagues can refer you so that you have better chances of landing a job.
