That might well be the case, but the trend is clearly visible. Customers are taking control. They are enabled like never before and it's more than blogs, it's mashups, vertical search, social networking and all the manifestations of Web 2.0, or the Next Net as it is also called.
It comes as no real surprise that these developments would affect travel. It has long been the largest vertical on the web and lends itself to the application of many of the technology developments mentioned earlier. You can blog about cars or DVD players but you're still not able to build your own, but you can build your own trip.
Of course, this opens up new options for indpendent travel agents by becoming enablers an facilitators, although my own guess is that the majority of those adopting Travel 2.0 will be independent travelers that are in a self design mode. Fascinating to observe how this develops.
