Careers site Fistful of Talent has a great article about the line between putting yourself out there on the Internet and going too far. Their anecdote? A job candidate who included a link to a porn site and landed an interview. How? He was a software development candidate who produced his own movies and wanted to demonstrate the fact that they were coded in all of the latest development languages.
So instead of the link causing the candidate's resume to be trashed immediately, the potential employer realized that he seemed to be a qualified candidate and deserved to be considered. Seems like a wise and fair decision in a sometimes rigid, black-and-white world that's really very gray. Sure there's a line that can't be crossed, but sometimes it's moving target.
