While the demise of Google Reader got all the attention, there are some other things going away in A second spring of cleaning. It’s worth reading.
Google certainly has the right to shut things down — and I think they’re right to do so, also. The company’s been all over the place and should continue to work on focus.
But I don’t like when they turn off existing support for an open standard like CalDAV in favor of a Google-only API. Sure, they can — it’s within their rights, obviously. But I don’t like it.
