I'm actually looking for any way to improve Harvester. Finding product-market fit is SO hard, so please let me know what you hate, love, would love to see.
It's been notoriously hard to get people to use "localised recommendation apps" like this. People often just go to Google/Maps and look at what's around. Sorry to link this, but it reminds me of [1] this YouTube video by YCombinator warning about these kinds of apps.
Anyway, I do love the original style used on the site, and it's obvious that you care about the product, so I wish you luck in finding product-market fit!
