One site that did an excellent job with frames is TV Guide . In fact, I was going to link to them here as a good example. But, guess what. They dumped the frames as well. It is hard to make a frame set which works well on different size screens and different browser window sizes.
Frames are very easy to mess up.
If you allow other sites to come up in your frame window and they link back to your site you may find recursive versions of your window getting smaller and smaller inside the window. Used properly frames can be a powerful tool and produce dynamic an interesting web sites. A lot more information on frames can be found at the Netscape Frames Introduction Page . This page includes many justifications for frames. Note that in running around the Netscape site I could not find any examples of frame usage at their site.
