Yeah, I feel like if you don't engage with the "social" aspects of it and just treat it as an easily-shareable resume platform, it works exceedingly well.

Though, getting to see an insight into the people you may potentially work with is also a nice touch, in some instances. You can get a good feel for the type of environment those people would like to foster in their workplaces, and make an informed decision about whether or not you'd feel comfortable working for them.
