Not sure if the site's being HN'd or not, but the signup failed and then when I resubmitted the form it said my username was already taken. Tried a password reset just in case, but nothing came through for that either. Lots of error 401's, 409's and 500's in the network inspector.
Cheers to admin for changing the title, but old title better reflected the last update (and I used it because Heroku doesn't have a permalink to each new update).
If you use https://larder.io/ with GitHub star sync enabled you can get weekly emails for new release notes. While it doesn't replicate the functionality demonstrated here, it's still a cool tool.
