Facebook Vanity URLs – Good or Bad?

Yesterday, Mashable reported that Facebook would begin offering vanity URLs (or usernames) this weekend. At first, I thought – cool… facebook.com/nicolevanscoten. But then I started thinking, is Facebook becoming even more like MySpace? Opinions on the Twittersphere are mixed, so I want to know – what do you think? Will Facebook just become full of users with “SexyGuy09″, or will the majority use it professionally?
Comment your opinions…
