I’ve got a side project going that’s a browser extension (starting with Safari + Sign in with Apple) intended to add a comment layer to the internet as a whole. I’m calling it Chaffiti (https://chaffiti.com).
The idea is to enable a comment section on any webpage, right as you’re browsing. Viewing a Zillow listing? See what people are excited about with the property. Wonder what people think about a tourist attraction? It’ll be right there. Want to leave your referral or promo code on a checkout page for others? Post it.
Not sure what the business model will look like just yet. Just the kind of thing I wish existed compared to needing to venture out to a third party (traditional social media / forums etc) to see others’ thoughts on something I’m viewing online. I welcome any feedback!
