This phenomenon hits me all the time because I'm an early adopter. There are many dgabriels in the world, and all of them think my gmail adress is theirs. I have gotten emails meant for theater directors, therapists (with very confidential info), been signed up for a million services (including adultfriendfinder and some Australian hook-up site). I get chain mail with puppy pictures from other people's grandparents, and yoga lesson confirmations, and invitations to participate in physician studies.
On one hand, it's a fascinating window into the diversity of dgabriels and their lives, but it gets irritating when I repeatedly get stuff after telling the sender I am not the droid they are looking for.
And, yes, I totally grabbed my outlook.com username, even though I don't currently have plans for switching...
