Look Ma, Not even a single table.

We've removed the last table that was holding the Site Logo. Now we've a pure tableless layout throughout the site. There have been a lot of discussion about using tables vs CSS based tableless layouts. Here are few links that will clear some confusion:

Tables or CSS: Choosing a layout by Craig Saila.
Why avoiding tables (for layout) is important by Dave Polaschek

For us the reason to make this transition was to make this site more accessible, more usable.
Also, the site now validates as HTML 4.0 Transitional and CSS. Another step closer to more accessible design.
