Safari rocks!
Well, it does! :) Because it’s the only f***g browser that supports CSS2 feat. called “text-shadow”! Firefox, Mozilla, IE, KHTML, etc. all flunk the test!
If you point your browser at Ubuntu Linux site and take a closer look at, for example, first heading entitled “Linux for Human Beings”, you’ll notice nothing special. But that’s only because your browser sux! If you take a look on the picture below, you can see how Safari and Firefox render the heading differently.

It’s seams that Firefox, or any other browser for that matter, does not support the whole CSS2 specification. Which is not good. If I make a site and use every bit of CSS2 to make it look nice, fast, usefull and amazing, I would expect that it would be rendered in the same way on every browser supporting CSS2. But unforunatly that is not the case. And as long as Gecko does not support those feats, Firefox users are at lost for a good, nice and amazing websites. And that just ain’t right.
So, Safari rox. Well, at least at CSS2 support. On the other hand it’s realy bad when it comes to javascript. For some reason every javascript app intended to help you write your blog, providing tags and WYSIWYG text-areas, does not work in Safari. And that just sux.
I guess there is no “The ultimate browser”. Every browser has it’s flaws, it’s just how many of them bother the user, that makes that browser suck/rock.
