Cons of social networking:
Computers drive me CRAZY!
Computers hate me.
They have tried to kill me several times.
Also sites like Facebook suck out your soul and are addicting.
Pros of social networking:
Mems are funny.
Facebook stock is a commodity.
You can reconnect to distant friends and/or family.
Summery: Over all social networks can be convenient useful and fun but I chose to limit my time on them because of all the insanity, death and soul sucking.
