Does preferring SW over Facebook mean you prefer the interests of strangers to that of your friends?

No, it means SW is better than Fakebook. (There is actually a real book called Fakebook [LOL!] about a fictitious walking journey the author took across the US. At the time he did it, he'd created a second account, and it was through posting on it that his friends and relations afar believed his story. Guy was thorough too, he looked up the time it would take to walk his trail. )
