Nobody knows you're a dog
So many times we might make a friend on facebook, myspace, or just in a chat room and do so because we don't want to seem rude or unfriendly. However, anyone online can say whatever they want about themselves and we would have no way of really knowing what to believe. This doesn't mean that only the crazy people online are the ones that lie. I think it's safe to say most people tend to fabricate or exaggerate things online whether it is to attract the opposite sex or a future employer.
Facebook
Would you add your Mom as a friend on facebook? My answer is yes. In my opinion, if you are going to be posting something online for hundreds of people to see but it's not even appropriate enough to show your own mother, then it probably shouldn't be posted. Because so many people have facebook now, you really should reconsider what you want on your profile and how you might be perceived.
