There were a few main things I noticed that were different between LinkedIn and Facebook. LinkedIn seemed to be very more professional than facebook and seemed as if it were more used for being looked at by a job interviewer or someone in the same field as me. It was much more about my own accomplishments and what I am good at and what I know. It seemed to almost be a way to brag about what I have done, can do, and know. Facebook seems to be much more social friendly and includes a bragging of a different type. It seems most people brag on facebook about what they are doing like traveling or vacationing or other fun activities. People include pictures of new gifts or new items they just received and/or vent about stuff going on in their life. It is a lot less professional than LinkedIn and a lot more immature (at least on my facebook news feed). I doubt I would ever see someone on LinkedIn posting something about drinking or partying or venting about ex significant others.
