So going on holiday, writing a blog about it and posting it on Facebook is narcissistic...yet going on holiday and checking in there just so it adds it to your places is fine?
Suit yourself.
Surely you can see the difference? One's screaming and making a big song and dance about it and making sure everyone and their dad sees it. One is a few words of text which can easily be missed when someone's going through their newsfeed: "such and such was at Brugge", and isn't any more narcissistic than checking in anywhere or writing a status update. They're all narcissistic to some extent as social media is generally narcissistic in it's nature, but some are much more so than others.
