The advantages of networks like Facebook makes communication extremely simple between mass amounts of people. This convenience is responsible for many people having tons of friends on Facebook and not really knowing half of them. This also creates the problem of having "fake" people pose on Facebook which is creepy.

Another issue that is brought up with Facebook is the massive amount of people that use the networking to try and drag you into their pyramid scams. I'm sure about everyone gets these messages from a guys who knows a guy who knows you. The messages usually consists of some friendly greeting followed by "I know we really don't know each other" and then a job proposition in which you can work your own hours with great pay and all that jazz. This gets annoying fast because of its constant recurrence.

I believe that Facebook is a great tool and has many advantages but these problems I have recently experienced bring the minor drawbacks to light.
