If the foo browser says "works like IE5" but then your page looks bad there, 
users of the foo browser are going to complain both to you. So "works like IE5" 
is an OK first step, but as a web developer you really want to know what 
browser this really is, because you can't trust browser vendors to really 
exactly be like IE5.

I guess that's why Adobe Flash had so much success. It really provided a very 
consistent experience across platforms provided everyone had the plug-in.

(I find browser strings fascinating. the sheer volume of 'I may behave like 
<x>' statements adds up to a mighty mishmash of things none of which directly 
relate to what I think web code developers wanted, although 'works in IE5' may 
indeed be "it")

It's not just a set of features. Sure, it all started with Netscape supporting 
frames whereas Mosaic did not. So it would be nice if it just advertised 
"Supports: frames". But then IE also supported frames, but if the graphics 
designer made a web page so that it was nice and pretty and aligned perfectly 
in Netscape, it looked all screwy in IE, because of differences in spacing 
within and between frames. So it helped to be able to serve different pages to 
different browsers. And then came active content, with Java applets and ActiveX 
and embedded video and javascript/vbscript, and things got worse. It's been 
getting better in the last few years, but not that much better than you can 
make a single version of your website.
