I'm only 19, and even I remember a time when Netscape was still pretty popular, or at least a lot of people had Navigator installed. It was even mentioned or displayed in a lot of programming books, articles, and presentations. I wonder how he managed to avoid knowledge of it for so long.
I'm guessing it's just one of those made-up stories by a journalist somewhere. According to Wikipedia Zuckerberg was doing programming in the 90's and would very likely have came across Netscape during that time. But, by the time Facebook was 'invented', Netscape had been basically non-existent in the market for a few years.
iirc I'm one year younger than Zuck but still remember upgrading to Netscape Navigator 4.0 from a previous version. But then again I grew up in SV and my dad was in the PC industry. Zuck grew up the the East coast, and that's probably the biggest difference.
