A good question. Let's have a look at how some of the people who have met him describe him :-

"I don't know if he's psycho, but he's certainly an elitist. And of the worst type because all he does is shout about our "ignorance" but refuses to explain his supposedly superior knowledge. Leads me to believe that he doesn't really know either. I wonder if he lives in a run down shack in Montana?"

"Jim Navas...ah ha haa haa haa, he's been flamed from one board to another till he finds one that puts up with his crap."

"I've seen this guy on the FIC newsgroups. He is insane. I hear he has a brother with a similar name that does know his stuff about something; not sure what, but hardware related. I think Jim is an overachiever trying to cast off the shadow his brother puts on him. Rule #1 when dealing with Jim Navas is address him as "King Navas" knower of all that is electronic."

So, does he know everything that is electronic? Is that why he's so infamous? Let's find out.
