Chris Mills of opera has just published great resource for web developers. In this he talks about best practices and tries to get people to unlearn stuff like:

In the old days, people used to do things like laying out their web sites inside giant tables, using the different table cells to position their graphics, text etc (not what tables were intended for, adds superflous markup to the page). They used to use invisible images called spacer GIFs to fine tune positioning of page elements (not what images are intended for, add superfluous markup and images to the page).

So go and check check (this new one, web platform) it out, it sure is a great resource and will get better.
