Do all web sites need usability testing?

An interesting viewpoint but the lack of Usability Testing has hurt many sites ...

"I’ve been lucky enough to have quite a few very educational and informative experiences with usability and user testing. I’ve found just about each and every one worthwhile and think I learn a bit every time.

However, recently I’ve been working on sites where I’ve done little in the way of formal user testing. From what I can tell, while not perfect (what site is?) these sites have come through rather well in the absence of formal testing.

It’s caused me to question whether, under certain circumstances, usability testing is needed for a Web site. I don’t know the answer, and in general I’d always recommend user testing if you have the ability and resources to do it, but I’d like to explore the idea a bit.

So what do you think, does every Web site need user testing? I’m going to say that, no, not every site needs it to succeed. However, I think Web professionals need it to help make better design decisions and I think that some user testing is better than no user testing if for no other reason but to help develop an affinity for the people who deal with our sites."   continued ...   (Via Web Design/HTML)
