Hey! I’m launching something called — a digital billboard for startups, builders and creators.

Share the vinyl records you're spinning and see what other collectors are playing.

I collect records and I build apps in my spare time (and listen to records while I build apps), and this is what happens when those two things run into each other. Many people post photos of what they have spinning on their turntables on social media, and most never get any engagement. It occurred to me that people might want a better way to do this, and bringing them together in a niche social site might help. So I made Wax Spinner. Connect your Discogs (the de-facto vinyl collector's catalogue) account, post whatever you're playing with an optional note, and it lands in a feed where people can like it and comment. You can also browse anyone's full collection on their profile, and filter the feed by genre, pulled straight from Discogs metadata. The conversation and the discovery are the primary purpose. The details this crowd might find interesting: every spin generates its own OpenGraph share card on the fly, with cover art, artist, year, and notes rendered server-side and cached

Share what you're working on. Get honest feedback from builders and potential users. Get inspired by the ecosystem.

Niceee. If you want to share it with other builders, get your first users, collect feedback, and test it out, we’ve just launched a platform for exactly that. We literally just went live.
