Linkedin is a business oriented social networking site.

Being a user of Linkedin says that your interesting in making business oriented relationships.

Advantages it has are everything is geared toward a group who is interested in making business ties and collaborating with other professionals

I cannot foresee any problems with this medium because it was built specifically for the subject at hand and i would probably need to spend a lot of time using it myself to come across any weaknesses.
