At this point Google has proven it only wants to focus on profitable ventures or those that tie into Google +. Any service/data aggregation that Google is solely depended on should be considered at risk of closure at any time, and such closure should not come as a surprise. Personally I am moving away from Google except for only the least valuable services; my email, calendar and everything else are moving elsewhere to paid services. It is the end of the age of innocence for Google.
