• What can CSS3 do? Basically, suck less than CSS2. Lots of text and background effects.
• "progressive enhancement" - the idea of a site looking different in different browsers - you write out all the specifications in such a way that browsers that can't support them simply ignore them.
• You can do some awful hacks in IE6 - look at http://css3please.com/ but consider stabbing yourself in the eye first
• http://modernizr.com - ways to push different code to different browsers
• What about everyone else?  Safari, Chrome, Opera, Firefox? iPhone? iPad? If it works in Safari, it mostly works in Chrome -- they're both WebKit browsers
• Browser makers are each implementing things that not everyone has agreed to
   -- and this is ok!
• example: -moz-border-radius: gives you rounded borders in some browsers, webkit-border-radius: get you others. There's also border-radius: which is the CSS3 version. Right now, do all three to cover the greatest number of browsers. Also as trivia: -khtml-border-radius: for Konqueror
• The CSS Working Group is creating the spec for CSS3 over time in 'modules'
• http://border-radius.com lets you play with border-radius ideas
