Working closely with designers and observing client requests over the past decade or so, I've seen another pattern that also leads to the "small type" problem: Client requests to get as much above the fold as possible. Granted, the majority of the projects I've worked on in the past four or five years have been very large organizations. When client committees make decisions, it's much harder to teach them or even steer them in the right direction.

I'm seeing a growing number of comments here that read like "I can..." or "I prefer..." The article clearly states this is a decision arrived at by considering the end-user. It's all relative; all sites don't need to be that way. You should be user-testing every project with your target market anyways, and if you were and it was a problem you'd hear about it. I know I have, many times.

Another great article on this subject is one "Relative Readability" by Wilson Miner:
