The article was complete and utter crap! Don't believe a word it says. It was written by someone who thinks "check the facts" means finding out what the letters in LZW stands for.
Png is a very popular format. It's the choice of the vast majority of the Gimp, PhotoShop and varius raytracer apps users.
Png is a format that supports 8-bit, 24-bit, and 48-bit graphics (plus alpha-channel). And it supports color profiles and lot's of other goodies. Gif on the other hand have nearly no features at all, except perhaps for animation and
only support 8-bit graphics.
Png is so feature rich that the jpeg group responded with the jpeg2 standard which was the greatest graphics format failure until this date (AFAIK). Chances are that you have never even heard of jp2 (or j2p, etc). Jpeg2 is however quite nice; vastly enhanced "lossy" image quality
and support for color profiles and loss-less saving. If people knew it existed png would be in big trouble :-)
Btw, png works just fine with the latest browsers (even Internet Exploder).
