But this is Google. They deprecate things with last week's milk. I feel like they have a pretty good idea of what's still running, and shut it down if it doesn't make them at least half a billion a year. I still miss many products, and I wasn't even a Reader user (so no, it's still other stuff I'm disgruntled about).
These days you can't even do a Youtube search without an account, and an account needs a phone number of course, so you have to resort to HTML scraping to do simple stuff like just using the top hit (so you can fire off a tab with some song in the background, without waiting for it to load and click a result with the mouse). There used to be an API for simple things like that.
