This is super neat and I think I've seen your site before :)
Do you handle authentication? We have lots of users that want to automate some part of their daily workflow but the pages are often behind a login and/or require a few clicks to reach the desired content.
That's not literally his e-mail :D. He means that you have to replace it with his HN username. It would have been better to write it like this: [HN username]@gmail.com
I'm also curious about this! I've been learning about scraping, but I've had a hard time finding good info about how to deal with user auth effectively.
