There are particular industries where web design seems to have not reached the 1.0 era yet (forget about 2.0). Usually these are industries dominated by small businesses. Small business owners are usually busy doing actual work, so they may not get to spend much time online and may not be up on the latest web trends. They may have heard about "social" and "SEO," but don't understand how it all works together and how you create a web experience that draws customers and enhances your brand.
One industry that's notorious for bad websites is restaurants. When a restaurant does have a website, there's a good chance it's out of date, parts don't work, or it violates several usability principles (e.g., it has a splash page, it automatically plays music, it's built all in Flash, or the menus are only in PDF). This isn't just about bad visual design -- although there's plenty of that too. These are things that actively keep users from getting what they need from a website.
A 2010 survey by the National Small Business Association showed that 16% of small business owners didn't have a website at all, either because they didn't think it was necessary or because it would be too difficult to build and maintain. Of those who had a site, 69% said the biggest challenge they face with their website is the time it takes to make updates. Thirty-nine percent said their biggest challenge was the cost of maintaining the site. So it appears that, along with not meeting the needs of users, websites for small businesses are not meeting the needs of their owners.
The solution to this problem may be to give up on the idea of "websites" altogether. Think of the restaurant example. A quick trip to MenuPages will usually tell you everything you need to know about a restaurant. You'll see the menu (in HTML and PDF), the hours of operation, the address (with a map) and reviews from other customers. MenuPages also now partners with SeamlessWeb to let restaurants offer online ordering.
Best of all, MenuPages' staff does all the actual site maintenance. Restaurant owners only have to send the site their information through a simple form, and then upload, email or even fax it a menu. In return, they get an instant web presence on a site that is visited by more than 1 million users per month.
There are other sites that offer some of the same functionality, such as Yelp, Facebook and Google. But currently, these tools don't offer many of the "website" features that businesses may want. There isn't always a place to put your logo or any pictures of your business. You also aren't usually allowed multiple pages for different topics, which would be necessary for many businesses.
Yelp, in particular, only provides the barest options for business owners to publish information about their own businesses. And while Facebook does allow multiple pages, the process is not intuitive, requiring you to log in as a developer and create a new "app" for each page.
It's odd that the bigger players aren't doing a better job of this. The potential is huge for a site that offers built-in search, SEO, e-commerce, content structure and mobile, all with a great design that was easy to use.
