This... is cool, but also kinda sucks for me. I've invested dozens of hours into writing an extremely complicated scraper for my Android version of HN.
This definitely does suck. I feel your pain. But it's also part of the package of scraping websites. You go in knowing that it could break at any time.
Oh, I'm well aware. I've had to push many quick fixes when some field gets renamed, etc. It's really not the API change that bothers me, more the lack of features. But hopefully they can add those things soon and I can re-enable them down the road.
