Can we just head this trend off at the pass? It seems that Kara Swisher and Walt Mossberg, at their “All Things D” conference announced the beginning of the Web 3.0 era.

That’s ridiculous.

And I’m not the only one to think so.

Short aside: It’s interesting that neither Kara nor Walt show up very often on friendfeed, which is the best example of the 2010 Web right now. Kara Swisher has made a total of five comments there. Walt is even worse, doesn’t bring any items in there, and only has six comments. How can you know what the 2010 Web is, if you don’t use it and don’t participate in it?

The Web does NOT have version numbers. Naming what was going on in the last eight years “Web 2.0” did us all a large disservice (Tim O’Reilly did that, mostly to get people to see that there was something different about the Web that was being built in 2000-2003 than what had come before).

But by naming it a number, I believe it caused a lot of people and businesses to avoid what was going on and “poo poo” it as the rantings of the new MySpace generation (which was just getting hot back then).

See, the Web changes EVERY DAY and a version number just doesn’t do it justice. Think about today, we saw Microsoft announce a major new update to its search engine, named “Bing,” that turns on next week and is already getting TONS of kudos. Seriously, in the rental car shuttle today a guy I met said the demo he saw at Kara and Walt’s conference was “awesome.”

Also today was Google’s Wave, which caught everyone by surprise and which sucked the oxygen out of Microsoft’s search announcements. Check out all the reports that I liked from around the world this morning.

But, back to the theme of this post. There IS something going on here. I covered it a few weeks ago.

The things that are happening are NOT just Twitter and search. Here, let me recount again what is making up the 2010 Web:

1. Real Time. Google caught the Wave of that trend today BIG TIME.
2. Mobile. Google, again, caught that wave big time Wednesday when it handed Android phones to everyone at its IO conference.
3. Decentralized. Does Microsoft or Twitter demonstrate that trend? Not really well.
4. Pre-made blocks. I call this “copy-and-paste” programming. Google nailed it with its Web Elements (I’ll add a few of those next week).
5. Social. Oh, have you noticed how much more social the web is? The next two days I’m hanging out on an aircraft carrier with a few people who do social media for the Navy.
6. Smart. Wolfram Alpha opened a lot of people’s eyes to what is possible in new smart displays of information.
7. Hybrid infrastructure. At the Twitter Conference this week lots of people were talking about how they were using both traditional servers along with cloud-based approaches from Amazon and Rackspace to store, study, and process the sizeable datasets that are coming through Twitter, Facebook, and friendfeed.

So, why doesn’t a version number work for these changes? Because they don’t come at us all at once. A lot of these things have been cooking for years. The Internet makes iteration possible. Tomorrow will be better on the Internet than today. In the old world of software you’d have to wait for the compilers, then you’d need to distribute tons of CDs or disks. That no longer needs to be done.

The idea that we have a version for the Web is just plain ridiculous. It makes the innovations we’re implementing too easily dismissed. How many times have you heard that “Twitter is lame?” I lost count 897 days ago.

Now, is using a year number, like what I’m doing, better? Yes. It gets us out of the version lock. And it makes it clear to businesses that if you are still driving around a 1994 Web site that it’s starting to look as old and crusty as a 1994 car is about now. Executives understand this. It’s a rare executive who drives an old car around. Most like to have the latest expensive car to get to work in.

Same with the Web. Calling it the “2010 Web” puts an urgency into what’s happening. If your business isn’t considering the latest stuff it risks looking lame or, worse, leaving money on the table. Just like driving a 1994 car risks looking lame or, worse, breaking down a lot more often than a newer car.

Is the year metaphor perfect? No, I’m sure there are a few things wrong with it. For one, if you want to host a conference based on the “trend” you’ll have to change your conference name every year. That costs money, which is why conference companies like to have more stable trends that they can exploit for a few years, at least.

Also, there are some clear “eras” in the Web, so I could see wanting to suggest that we’re in the third era of the Web, but I’ve been studying this for the past eight years and calling the second era “Web 2” actually held us back because mainstream users didn’t think anything was happening in the past few years and Web 2.0 became a useless phrase anyway.

Anyway, can we use year numbers to describe the Web now? It’ll make it easier to evangelize the modern world to businesses. We’re entering the 2010 Web, that’s what I’m exploring. Calling the Web a version number is for people who don’t really understand, or participate in, what’s going on here. Kara and Walt, you gotta do better here.
