Looks like a coding project with no usefulness
Some constructive feedback: - There is no search - which means its not very useful. - It loads just 3 images at a time. That's a lot of clicks.
1. Find your DNS Target in heroku. It should end with .herokudns.com
2. Lookup the historical DNS record to get the IP addresses. You can find historical DNS records here: https://securitytrails.com/dns-trails
3. Replace your CNAME record in your DNS provider with A records that point to the IP addresses you just found.
Your site should come back up shortly. We plan to revert back to CNAME records once Heroku gets their DNS issues sorted.
Keep improving this and with the rise of web personalization, the demand will continue to grow.
We've spent a long time establishing landing page messages so it makes sense to users as soon as they get there - otherwise they just bounce, including HN users! I've not signed up to try this out, but there is just not enough info before asking a visitor to sign up. So may want to add some info there on the value prop?
