"I learned about post-tourism, which is just research jargon for traveling hipsters: believing there’s no authenticity left in the world, they enjoy tourist attractions ironically."

From "Thomas Cook and the Stack Pirates/Boredom and an enterprising Brit gave birth to the modern tourism industry, and we’re still trying to make sense of it all" by Mary Mann (via Metafilter). I'd never seen the term "post-tourism" before, and there's lots more in the article than that idea, including the process of doing research in a library...

Modern tourism started in England, which makes sense — a colonizing country is probably a restless country — but by the mid twentieth century people from all over the world were touring. Tourism became a thing; you could tell because people had started studying it. The stacks are full of their books: The Ethics of Sightseeing, The Language of Tour­ism, The Tourist Gaze, and so on for longer than you’d care to read. Before venturing into the stacks I’d never read a book on tourism, but I knew the industry from working in it, first as a guide and then as a copywriter....

The long chatty article ends with another reference to "post-tourism":

It would be easy to admit defeat, to become the “post­-tourists” researchers write about, committed to the idea that there’s no such thing as authentic experience so we might as well laugh at it all. That seems like the most boring fate of all....

The parishioners who came to my dad [a pastor] for ad­vice all asked versions of the same question: How can I be free? Free from grief, from anxiety, from anger. Free from the purposelessness of boredom, the result of a dull job or a stale marriage or the tedium of too many identical days in a small town. But, depressed, my dad wasn’t free either; so there they sat, week after week, year after year, prisoners theorizing about their chains. Travel, at least in the books I read, offered to press pause on those questions in order to ask a single question that, if it could be an­swered, would make it one hundred times easier to figure everything else out: Free for what?

Notice that this idea is that ordinary life is a problem and travel helps by removing you from ordinary life, perhaps to give you a new perspective on ordinary life. But if ordinary life is not, for you, a problem — not everyone is depressed — then perhaps you do need to confront the problem of authenticity, because ordinary life is (probably) authentic, and perhaps the answer is post-tourism. 

Here's another article on the subject: "Authentic outsiders? Welcome to the age of the ‘post-tourist.'"

“Post-tourism” is an ambiguous term, certainly, but it invariably suggests something of a departure from everyday “boring” tourism. The rise of the post tourist – as an offshoot of the dreaded hipster and their avoidance of tourist hotspots and maps – is symptomatic of this “tourism-as-performance” phenomenon....

Post tourism abides by narratives of self-righteous struggle, “tourist-shaming” those who continue to visit predictable tourist spots such as the Berlin Wall or the Eiffel Tower. Hence, post tourism is partly defined by an underlying sense of posturing where travelling is concerned.... Any traveller or tourist in another country inevitably remains an outsider.
