I've been thinking a lot recently about Web 2.0, technological innovation and the UK. A lot of it is due to my sudden twitter fascination (follow me @ twitter.com/jwheelhouse), really getting into Revision3 shows such as Diggnation, Tekzilla and Systm, and not forgetting the first podcast that really got me hooked - GeekBrief.tv.

All of these Web 2.0 services originate from the US. That got me thinking and I thought I would do a little digging to see if I could find some UK originating web 2.0 services. Now it would appear that Last.fm is the biggest success followed by ShoZu. There of course be many more that I am missing or I am simply unaware of their origins - if you know of any please post a comment.

Don't get me wrong, its not that I don't enjoy using US based services - I wouldn't use them if I didn't! But I have to ask why Web 2.0 start-ups don't come from the UK, in fact can you imagine a company like Revision3 even making it off the ground? Is is our broadband infrastructure, our fear of trying something new or simply a case of being beaten to it?

Any thoughts? Do you run a UK Based Web 2.0 Service? Answers on a postcard, or failing that in the comments below
