Let's draw an analogy here. Let's say that Google decided to conduct an experiment on its Glass users, and that for a period of a week, Google decided to see if it could alter the mental state of its customers by using Glass to delete or diminish positive social interactions. Let's assume this research was conducted without any kind of consent or knowledge of the customers being experimented on. What's your immediate reaction to that? Still cool? Still harmless and just like advertising and A/B testing? Or, creepy and dangerous?
Like it or not, Facebook does have a special responsibility here. It is, quite literally, the lens through which people see their world.
Google Glass absolutely will have to carefully rank the content that is displayed on its interface. The algorithms for such ranking are surely ripe for R&D and competitive advantage, and as such, will be constantly evolving and being tested. If this Facebook test creeps you out, there is literally nothing about Google Glass which should NOT have you running for the exits.
onewaystreet did not say advertising was harmless; rather, the opposite. It's interesting that you think advertising is harmless, not creepy, and not dangerous.
