Unfortunately, I share a name with a film director, a cricket player, and a bassoonist for the LA Philharmonic. I wouldn't want to take the chance that they'd find the wrong person's profile.
The idea behind "google me" is that YOU are the only person that shows up. You've got to work to get there. Once you've gotten there though, it's a nice place to be. Without trying very hard I was about to take my blog from 30th to 2nd when you search for my name. I'd love to dominate all top ten spots with different examples of my work.
Not if your employer is trying to screen hundreds of candidates a day (as attractive big companies are). Anything that requires extra work just gets thrown out.
That sounds incredibly arrogant. And unless a google search of you turns up some amazing accomplishments you will end up looking like a fraud.
