Facebook Paradox: real social or unreal social

Today a post at TechCrunch blog caught my eye. From an official Facebook business letter to one user, it said that Facebook "expect accounts to reflect mainly real-world contacts" in contrast to "mainly internet-only contacts." Wait a minute, is Facebook an online community or an offline community?

I think the letter reflects the paradoxical thoughts among Facebook executives. In short, they are expecting to clone the real social network among real people onto an unreal world. What a mess of thinking!

Facebook, if you think yourself is real, please also respect the internet-only friendship be real too. Otherwise, isn't Facebook an internet-only platform of social networks?
