Where do we go from here?

Yesterday a friend used the phrase 'Web 3.0'. I think it was the first time I'd heard it said and it made me wonder if we are on the verge of the third age of the internet. Web 1.0, or just Web as it was known ,was a bit rubbish, (in hindsight) a bit beta, but Web 2.0 has been an unqualified success - Facebook, Twitter, Youtube, Wikipedia, Google and all its spinoffs etc. that we now use day in, day out, without a second thought as to quite what these services are actually offering us.

Web 3.0 though. What's it going to be? Wolframalpha? Google Chrome? I'll admit I don't know what it will entail, or does entail already, but it seems likely that as we hurtle towards 2010 the phrase Web 2.0 will start to look outdated, especially to the new generation of technology developers who will soon be arriving on the scene, aged 15 - 21, who will no doubt design and develop the next web successes. It should be an interesting time. The future usually is.
