>What were people actually saying by Tweeting about their visit?

They are telling others about their life experiences. It's called communication, we do it in real life all the time, why can't we do it online? If somebody told you what they did on the weekend, do you respond "you are fulfilling your obligation to have to share"?

The crux of the argument seems to be the time and place of sharing. Before the advent of social media, sharing used to happen after the event. Now, it happens during it. The author doesn't seem like he is against sharing in general, just the sharing that interferes with the sensory experience of the event itself.
