I think you can have moderate success by copying something else, but if you really want to knock it out of the park, you have to do something different and take chances.
DeepShit.rocks is a free quote discovery site. The collection currently holds around 120,000 quotes across six languages: Spanish, Portuguese, German, Italian, English and French. Coverage is uneven — Spanish and Portuguese are by far the deepest.
Every quote is displayed over a full-bleed photograph. You can download any quote as a 1080×1350 image sized for Instagram, copy the text, or share a link that opens the exact same quote for whoever you send it to.
Each visit picks a quote at random and pairs it with a photograph from Pexels, chosen from a keyword bucket for the quote's category. The language menu in the header switches the whole experience. Every quote has its own address.
Photographs come from Pexels and are credited to their photographers in the footer. Quote text is attributed to the person or work it is ascribed to; attributions in public quote datasets are not always reliable.
