Table-based, Flash-heavy, browser-specific design is at least 5-6 years old and no longer acceptable. If you are still doing this, please stop.

Semantic, standards-based, accessible, table-free design is now the expected standard when developing for the web, and has been for awhile. If you are not already doing this, why not?

Interactive, responsive, no-load, taxonomical (folksonomies), adaptable design is the new expectation and has been around for a couple of years now. If you have not started doing this, better get to work.
