As the owner of a web design company, nothing drives me crazier then websites that are outdated or non-functional.
Looking for a good example, go to Perciption Kayaks. Under "Resources" they still haven’t added the promised forums that were supposed to arrive in 2004. They also have two "Sponsorships" that I have been also waiting to learn about from that era as well.
Now, I completely understand old content on sites, it happens. But if you are not going to offer something, just take it off the menu item. If it isn’t there, nobody will ever miss it.
Want to see a great site? Go to Jackson Kayaks. Visually it is OK. Nothing to big or exciting but they have fully embraced all the technology that the web has to offer and they have kept the content updated regularly. You can find a regular podcast created by Erik Jackson and taped it into itunes so you don’t need to go to the site to get the update, you can get it automatically downloaded into you computer through itunes.
The crowning section about this site isn’t even big or obvious. Look at the site and see how much acknowledgement there is to you the customer. They take the time to post user submitted photos and bring a family flair into the "Family Corner". By truly acknowledging the customer working to embrace them in their business model, they have created a very strong bond between company and customer.
