Everyone has an opinion on Web 3.0 lately. Personally, I think they are all wrong. And while I won’t profess to carry the official definition of Web 3.0 (personally, i think the definitions are stupid and misguided) I’ll tell you what I think the future of the web holds.

Web 3.0 will be a mobile web revolution.

There, I said it! Write it down, in the very near future the mobile web will come into its own. Right now, the mobile web basically sucks for anyone without an iPhone, and even then it is only marginally acceptable. The iPhone does a good job of letting you view the "regular web" but lets face it, most websites are not optimized for mobile viewing or even mobile features.

If you are looking for an example of what I am talking about, think about Google maps for the iPhone or even the WiFi iTunes store. In the future we’ll see more of these kinds of mobile optimized services.

At lunch today with coworkers we had this discussion. I said I thought Web 3.0 would be all about mobile, social networking. But upon further reflection I realized that in the past, the different iterations of the "web" were about technology and delivery, not content.

This is where I think people get it wrong. To me, Web 2.0 is about interactive, self updating web pages using AJAX. It is about building web applications and services that run in-line on the page, don’t require reloads and the pushing of information to the web visitor.

I’d like to thank Jason Calacanis for starting the discussion, but in fact, Mahalo isn’t Web 2.0 or Web 3.0. Mahalo is something like, Web 1.1. Web indexes maintained by hand is hardly innovative or deserving of being the poster child for what’s next with the web.

Expanding on the promise of a more mobile powered web, consider these scenarios. You have an iPhone or some other similar device. You walk into a store and your network switches over to the in-house WiFi. Now you’re online and browsing an interactive, web delivered catalog. Maybe you want to know where to find a certain product (in a department store, etc). A map pops up on your screen, showing your current location through GPS, along with a directory that you can search or browse.

Or, think about a Google of the future where no matter where you are, you get search results tailored to your location (based on again your GPS enabled phone). This is done to an extent with Google Local, of course, except you have to specify the zip code or cross streets. In the mobile web future you won’t need to do that though because the website your on will be able to access that data.

Social networking will also benefit from mobile devices. See where your friends are and create those social contacts based on location. Which of my friends are near the office today so I can set up lunch? Whats going on in my community today at a time that I have free on my calendar which is close by? That sort of thing.

There are thousands of examples you could come up to show how a company could serve its customers through mobile devices on its website.

The iPhone was a great start and has gotten the creative juices flowing about what could be possible. Obviously there are other companies out there following Apple’s lead now, coming up with their own devices.

It is simply a matter of time before websites start catering directly to the users of these new mobile devices, and that is when we will truly see a new "web" emerge. Some really progressive companies have a head start. Facebook (with its mobile service), Twitter (keyword tracking over SMS) and Flickr (geocoding of photographs) all come to mind - Wikipedia locking off edits to their encyclopedia definitely does not.
