A list of recent web design trends that are about to jump the shark:
1. Obsession with rounded corners everywhere.
2. Pastel colors.
3. Linear blends.
4. Fonts bigger than 15 pixels.
5. Avoiding tables, when they are the best solution.
6. Stretchable text columns that are too wide to read comfortably.
7. Ajax use that makes things difficult to link to.
These things are so commonplace now that sites designed this way seem like the web design equivalent of a fashion victim. When the bubble bursts there will be big pastel shade mess.
