For me the fact there are 1 million pictures of that clock online is irrelevant. People follow others on Instagram either because they are interested in what the person does or they find the other places and pictures interesting which have been posted in the past and would like to see more.
No one can see everything in the world so it is more like curating it, you follow a bunch of curators, see a bunch of stuff, for some stuff a photo is enough, for others it makes you want to see it yourself.
I have had loads of travel ideas from Instagram and have visited lots of places after seeing posts on Instagram.
This tempts me to go grab a set of "Prague tourist photos" and just make up a fake trip. Just be upfront: I didn't take a trip to Prague, but here's what it would look like it I did. Just as curated, just as personal, just as compelling as any brochure. Oh look this guy who's into craft beer and chess history wrote up a hypothetical trip to St. Petersburg, check it out.
Or better, a startup idea: tell us where you're going on vacation and we'll produce your social media posts accordingly. You just enjoy your vacation and we'll get you all the likes.
Or tell us where you want to pretend you went and we provide a fake vacay with which to wow your pseudo friends.
Bonus points: You can market your service as "eco friendly" and actively encourage people to admit they used it. There can be footnotes cataloging how much smaller their carbon footprint is for having only pretended to go.
