Good platform. A similar one was made I used to use back in ~2020 but eventually I think it died.
The best addition would be to have a simple form where people can submit ideas for questions. It'll keep your site from being stale and fading out of relevance like the last one.
Glad you like the platform! You make a good point about keeping content fresh.
I think the standard YC questions are the most high-value to practice, so I want to keep the list curated rather than open it up to the public right away (to avoid noise/duplicate questions). However, I will make sure to keep the database updated as the 'meta' changes.
