I wonder if it would be worth the money for Google to keep services like this one running, just so that people (especially enterprise customers) don't lose faith in Google's competency with regard to long-term product support. Although if you ask around here, you'd probably not find much faith for them to save.
I honestly don't think people outside the HN echo chamber care that much.
Sorry, but "We'll give you 12 months notice!" is still nowhere near "enterprisey". Try a decade.
