I said this either in late 93 or early 94. I was in a class when someone demo'ed Lynx to me, and I tore into it and the WWW. Looking at the timeline it seems that Mosaic came out right after Lynx, but my memory of it has Mosaic coming out way after Lynx. And it seemed like Navigator years after that, but the real history is super compressed. By the time I'd seen Mosaic, I was then pretty convinced of its utility.
