(Although my name isn't obviously unusual, it's actually more or less Internet unique and, at a minimum, I have a way bigger footprint than anyone else.)
ADDED: Personally it's probably advantageous to me to have a unique online identity. But it means I can't hide behind an excuse that "It must have been one of the other $NAMES that you read about." And I assume such conflicts could get a resume tossed pretty quickly by a recruiter doing a quick search.
The worst alternative is to have a name conflict who might be plausibly you based on location etc. where the other is a criminal, etc. I went to school with someone who shared a name with someone in NYC who was in very public and messy legal problems. He literally got death threats left on his (pre-Web) telephone.
Feature of a rare last name (two farmers in two different parts of Norway independently intentionally picked the same misspelling of a more common name to set themselves apart from nearby farms about 200 years ago; only descendants of those two have my last name, and half of them are related to me) coupled with a relatively rare first name.
Annoying when it comes to anonymity, but sometimes it's nice being able to be identified by name alone.
I love having a modern-day superpower: online search anonymity. I have one of the most common firstname/lastname combos in the western world. I don't seen to show up on Google at all, even if you include my middle name. The last time I tried the "search for yourself" experiment I got to about page 200 of Google results that weren't actually me before I gave up. Combine that with my avoidance of social media, and it's like I'm off-the-grid without actually having to be off-the-grid.
Shortly after that, two people (an actor and a prominent academic) with the same name completely overtook me.
