Good point Paul and illustrates the value of getting that essential 'buzz' and rapid/massive adoption. Google's acquisition recognised that although it had an equally viable delivery mechanism, the adoption levels were way behind YouTube, possibly because users weren't associating the Google brand with video search and delivery. There is no doubt, in this instance, that video search will attract serious ad revenue going forward and I believe there is some really, really clever R&D going on in extracting metadata from visual content, beyond user generated tagging. How many YouTube's do you think we are going to get out of this bubble?
