Claude Code Daily... Version 3 is live. Just shipped a clean refresh of the daily landing page: tighter flow, better signal extraction, and a soft CTA at the bottom that points builders toward without being pushy. Last week I dropped the previous version straight into the Claude Code subreddit. Result? ~400 visitors, only 5 clickouts. That’s how i test and iterate on Reddit. never blast a direct product link. You share the actual value first. the blog post itself. and let the equal exchange do the work. If someone finds the daily brief useful and wants to go deeper (beyond basic scraping into real intent signals), the path is there naturally. No deception, just reciprocity. builder mindset in action: ship fast, measure honestly, refine in public. does V3 hit cleaner? Drop your thoughts below.

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
