You misunderstood, completely. I never indicated that I don't have any FB/Twitter/Skype/... accounts.

The idea of having a secure communication channel doesn't mean that ALL your communications have to be over secure channels, that would be ridiculous. Having the option to bank on a secure channel for conversations you deem private is a perfectly reasonable compromise. People in government agencies switch between insecure and secure mediums regularly.

Having a FB/Twitter/Skype/HN account just means that I am willing to make a tradeoff of privacy to use these services, one that I am okay with. This does not completely exclude me from occasionally using a secure medium, right?

So you're using FB to communicate with family and friends. As far as i know Facebook messages are not encrypted. Then NSA could use these messages against you (you said this). Am i right?

Yep, you got it! Once again, I don't encrypt all my conversations because I'm making a tradeoff, but I would definitely prefer that they were all private. And again, having a distinct communication channel that was private would not be unwelcome.
