I've read the article and I really think, that's stupid to check the candidates social network profiles. Whats the matter if someone drinks beer with friends, or likes any kind of music? If someone hires you or not because of your social network profile, then that person has no sense of business. If someone think that is important to have a nice-safe profile, maybe we should all suit up, and start taking pictures of us reading some really hard books, or using the product of the hiring company. Or even better, we can wear a t-shirt with the company logo! Maybe the Y Combinator logo in your profile?
