I would definitely recommend adding example images directly to the main page, along with the link to the example trip. Otherwise there's nothing really to draw users in to using if they have to go searching for how the experience looks like.
also just because your landing page now has an example featuring singapore - this is my guide to singapore http://swyx.io/sg-guide and i feel like encouraging people to make opinionated guides to where they live is kinda nice and under explored
I agree with you, though you might think about contributing to wikitravel too. This is their Singapore page: https://wikitravel.org/en/Singapore
curation definitely is underexplored and I'd say we're seeing more of that in the future given the AI slob that's hitting us.
Also let the user do something without them making an account or verifying an email.
Thanks for your suggestion! I was hesitant at first cause it was under heavy development so anything I put there on main page might get outdated very soon. I'll add them very soon~
