no matter how many times I read this, I'm always slightly caught off guard. The image many people seem to engender of fb is one of a public service -- ie they only "see" their friends on fb, not some abstract CEO.
With that reasoning, it makes sense that people pour so much blind faith into the Web site as they do -- they simply do not see a corporate structure to their giant online playground.
I expect Facebook to archive my profile and everything I've ever posted there or publicly. I don't really expect them to archive my private chat and not give me a way to delete it.
