Interesting point, but most players in the IoT space are probably going to be platform-oriented and as such are likely to be more interested in serving APIs to other apps than putting their data and associated services on the Open Web. As such this huge flood of data will further reinforce the emerging dominance of the Internet of Apps.
In any case, Hossein’s post was about free expression of ideas, not about sensor dataflows. However, there will be many second-order effects from the IoT that may somehow support the open web, perhaps via improving content discovery via improved semantic and contextual analysis.
