It’s not that hard to pretend to be someone else. We’ve all done it. You know you’ve tried to do a Michael Jordan move and stuck your tongue out and everything. Okay, so maybe not Jordan, but someone else.
Theoretically, it’s a normal thing. Identity experiments typically happen during adolescents. It actually helps us to become more ourselves.
But you have to read this story on TechCrunch on how another Michael (Arrington) pretended to be Eric Schimdt on Facebook. He highlighted security issues, but one thing stood out to me. He pretended to be someone else, and as easy it was for him to do so, it’s just as easy for someone else to pretend to be you.

I miss the days when Facebook was open only to university/college students because it was that much harder to create a “fake” profile.
I remember those days. I had to input all the information for the college that I was working at – at the time. Those were different times. Do you interact with many “fake” profiles?
