I like Roman Mittermayr's breakdown of culture2.0 - I've been hoping someone would come along and help define what gives all these recent applications and websites their unique look & feel. Some of his obseravations include:

... Frankly, I also prefer rounded shapes over tight rectangles. Same with women, I guess... To try a “psychological” approach to this difference, I might point out these facts:

• Rounded shapes look more inventive, younger, flexible and experimental
• Rectangles do impress with professionality, big-business, trustworthy...

...It has become a must have. Footers. Most users don’t even notice them. You might have never clicked on one as well. But still, they need to be there to make a site look professional. Without them, everyone assumes you run a personal website. Believe or not, try and see yourself...

...Johnny Cash is dead and big fonts are back. I wish it was the other way round, but let’s get ourselves updated to 2.0 and accept oversized fonts....

But, of course, he's gone and made a mess by spouting some incorrect data:

Simple Web 2.0 content is made out of lists, paragraphs, HEADINGS (very important) and non-javascript links. Very simple, isn’t it. Another benefit of using this approach is a better integration into search engines. Check out SEO forums and you’ll find truth. Google loves basic websites. You are a Google hero if your website starts with simple H1-like headings. Try yourself.

Googe hero, eh? I like the catch-phrase, but, as always, mythology about SEO persists.
