There's absolutely NO reason for this

I've come across this type of message a few times recently, from any number of different web sites. (This one is from a company touting themselves as the "Leader in Media and Marketing Relationship Management") It makes me nuts!!!

Ok, I'm using Safari. Fine. It's version 3, and it's more standards-compliant than that IE atrocity. So, I have no tolerance for your inability to support and test on it. Also, I've got Flash 9.0 r11, so there's no reason to complain about a missing plugin, either. Unless, of course, you're too lazy or not clever enough to write proper detection code.

Get it right, people. No person using the web should be subjected to this.

Usability vs. revenue? Nope. Usability = revenue.

It is this battle between usability (simple and clean) vs. revenue (balance between getting what you want vs. being cluttered) that is constantly fought behind the scenes.

It's interesting that there's a perception that making a site usable is separate from doing revenue generating activities (like adding banner ads or splash entry pages, as was pointed out at Forbes.com. Even more interesting was the idea that there exists in many companies a battle between the two.

I'm not really surprized. But, I do know that there are more and more "enlightened" sites out there. They understand that usability is directly tied to revenue. Usability goes up, revenue goes up. And the other way around. Adding a few banner ads might get you some small short term revenue gains, but if you upset your paying customers, they're gonna go somewhere else (unless of course, your site is devoted to banner-ad seeking customers). There might be a few web sites that people will continue to go to even when they're hard to use, but yours probably isn't one of them.

There's lots of good examples out there, like 37signals. Take a look. Then make sure that your usability effort isn't competing with your revenue.
