Boxes and Arrows just posted another interesting article
that is sure to spark an active discussion... once you're able to post feedback to it without their server crashing, that is. Very ironic once you read the article and reflect upon server errors from a whimsical/delightful perspective...
Personally, I think the author has been watching a little too much MTV and not enough Discovery Channel. The technology gap between upper, middle and low-income America is gaping enough, not too mention the enormous technological disparity between developed and underdeveloped countries. It is highly unlikely that all technologies will ever be available to all people. As such, delight is going to be relative to the technology situation one is in. If you happen to live atop the technology mountain, you may certainly be more likely to find delight in the whimsical. However, you'll be the exception, as most people will live beneath you and find delight in the practical.
I'm no seer, but I suggest we stick to the fundamentals and continue to design user experiences that facilitate end user access to the information they need the most until such grandiose prognostications come to fruition. The key to successful web design isn't sophistication and whimsy, its simplicity. Until we begin finding that our users are calling for more whimsical delight in their interface experiences, the best way to serve them is to simply meet their needs.
