Bubble Spike?
People are starting to wise up to the distortions of bubble math surrounding the recent rush of interest in socially oriented websites steaming ahead under the banner of Web 2.0, but it is interesting to look beyond the hype to get a qualitative glimpse that something significant is indeed happening...
