As I acknowledged. But what they did originally is only a fraction of what's required for a browser these days. Saying "KDE did it" today is like saying "look, the Wright brothers built a plane! You can, too!".

Back then, the web was simpler and so we had many different engines. Today, we really only have two. All other attempts have failed - even Microsoft couldn't compete. The only reason Mozilla is still going is because of their head start and Google money. If Apple hadn't picked up KHTML and turned it into WebKit and Google developed their own thing, KHTML would be even more dead than Gecko is today.
