Your situation may not be the same. Now with that caveat, I'd say stick to middle of the road. The fancy schmancy stuff can make your site a mess for regular folks. Get yourself a copy of the Opera browser. If your page looks okay in Opera it will look okay in almost all browsers.
Opera does support some of the fancy stuff.
So you won't be in a totally dry mode. I've seen websites with bugs that chase the mouse cursor. But I didn't buy anything, read anything, or even remember the name of the website. It was fancy and if that's all they wanted then fine. But if you have a message to convey, or a product to sell, or a point to make then stick with the basics.
