I just found this nice portrait of Jakob Nielsen in an article at the BBC News site.
The article is about a web design exhibition at the London's Design Museum called Web Wizards, featuring Joshua Davis, Yugo Nakamura, Danny Brown and others.
It seems that Joshua Davis doesn't quite appreciate the work of Jakob Nielsen:
"He rubs me up the wrong way. By saying we should all embrace standards, he would create an internet where everything was concrete and unforgiving. His ideas don't promote growth, they stifle creativity. We are at opposite ends of the spectrum."
"I once sent him an e-mail - that he probably still has - saying that I'd beat him up if I saw him."
