Nick is a wise-cracking milanista who came here mostly with the intent of pissing on all the juventini here. He created the thread after the 2003 CL final.
Over time, it became a dumping ground for any and everything -- all topics under the sun. It also earned a reputation for running gags, lewd photographs, insults, jibes, and many things against the site rules that were less strictly enforced there.
Over time, people would stumble in it and ask newbie 101 questions and took on newbie behaviors - which became a headache for the more common posters there. So password protection was added (the nature of the content being another reason).
In time, however, the thread grew large and slow on the site. People posted there less often. And even the namesake Nick himself foolishly got in flame wars in other threads and found himself repeatedly, and ultimately, banned from the site anyway. In the meantime, the "What Are You Doing Right Now?" thread largely took its place.
You can still see Nick's profile:
