Job-Based Social Media Company LinkedIn"
Oh. It's that what it's for?
A while back, when on the point of leaving my then job, I set up a LinkedIn profile, as a mate who'd recently changed jobs himself said that a lot of employers these days look at the LinkedIn profile of prospective candidates.
From what I've gathered on the few visits to the site I've made since, LinkedIn seems to be a bit like FacePuke in that you add as 'connections' anyone you've ever nodded to in passing, in the canteen, anywhere you've ever worked.
Having thus built up a 'collection of connections' numerous enough to demonstrate to future employees that some remunerable use for you has been found in the past... er... well, that's it really. That's all it seems to be for. Unlike FacePuke there's no expectation that you 'interact' with the heads in your trophy cabinet in any way so, as far as LinkedIn is concerned —that's you done.
LinkedIn is also a bit like Twatter in that; after signing up, you will continue, ever after, to receive emails from them trying to tempt you back to the site with the news that someone you've never heard of has published an article about something you've no interest in and didn't actually know existed. I think this is where the monetisation angle comes in because these emails also invite you to a free 30 day trial of LinkedIn Pro which, I believe allows access to even more irrelevant and boring articles, in return for hard cash.
