We were having a conversation at home a few days ago about whether it was reasonable to complain about hipsters but at the same time, want to show each other viral videos that we hadn’t each other seen.
As is mentioned in the comments, obviously there’s a difference between liking something because you actually like it and because it’s currently popular.
I think it’s probably best to disregard whether lots of people like it, separate annoying bits of fanboi-ism for the actual thing.
If it’s a good thing, you should be happy to introduce your friend to it, and there’s nothing wrong with wanting to show them new things rather than old stuff.
Of course, it’s also ok to occasionally joke about hipsters and fanbois! 🙂
