The news is kind blowing this up bigger than it really is. But I find this as a good thing because I've noticed a few people FINALLY taking the advice I've been giving for years now, and that's to freeze your credit at the big bureaus and some, if not all, of the smaller ones.
That being said, I checked this data dump for my own data as well as a bunch of friends and family. Not a single person I checked was in it... Which is why I'm not finding this breach to be that frightening personally. The ATT breach was way worse. Also Krebs posted on this today... A good read for anyone interested. Main thing I took from it was a large number of these entries belong to people who have passed away already.
As a Gentoo user, I can confirm I started from sticks and rocks. I'm now in the space age though because of the customizability and performance boosts, so image is a little dated.
