The Dot In Your Gmail Address Doesn’t Matter - PSA

Sarah Perez posted an article on TechCrunch some hours ago saying, she's being receiving another person's messages since 2008, she wrote: 

"...a woman named Sarah Perez is probably very frustrated by technology. No, not me, a different Sarah Perez. She signs up at websites to receive information, and it never comes. Friends invite her to gatherings, and she never hears about it. She tries to reset her password, but the password reset never arrives. You see, Sarah’s problem is that, since around 2008, I’ve been getting her email."

You just have to realize the dot in your Gmail is nothing but a freak.. She continue saying, " I don’t know how the problem started exactly, but the other Sarah Perez can’t seem to remember her email address. It’s not sarah.perez@, as she mistakenly believes. The dot doesn’t matter – the email still comes to me."

So you think this is a bug or what?
