I don't think merely avoiding google glass wearing people will help much. To be effective you should probably avoid anyone with a phone/tablet that is not in their pocket and stay out of public spaces (maybe live in the woods).
Why not complain about Gorgon Stare instead? Since it is more likely to be used for infringing rights and you have more of a legal case (preventing unwanted photography in public was lost long ago).
>"The system is capable of capturing motion imagery of an entire city, which can then be analyzed by humans or an artificial intelligence, such as the Mind's Eye project being developed by the Defense Advanced Research Projects Agency. [..] It is a spherical array of nine cameras attached to an aerial drone." -http://en.wikipedia.org/wiki/Gorgon_Stare
That being said, I think widespread cameras are simply something people are an inevitability that people are going to have to get used to, warts and all.
It's really the scale of the thing -- YouTube and Ustream and the like are going to have some serious privacy concerns when masses of people want to start lifestreaming.
Of course, I should disclose that I became greatly interested in (at least partially edited) lifeblogging once I saw devices like the vaporwared Zion Eyez[1] or the Memoto[2].
I attempted to start recording my drives home with my phone and publishing them on YouTube, but I'm not committed enough to keep it up until it becomes frictionless. This would be a perfect example of the potentially scary surveillance -- if a number of people start autopublishing dash cam recordings, it creates a way for people/organizations/governments to data mine someone else's data for their own surveillance purposes.

We're all going to have to get used to being sousveilled.
