As part of the maps update announcement last night, Google noted that it would be retiring Latitude, just the latest in a string of high profile service closures including perhaps the most missed: Google Reader. Unlike Reader, Google seems to have some fallbacks in place:
One important change you should know about is that Latitude and check-ins are no longer part of the new Google Maps app, and will be retired from older versions on August 9. We understand some of you still want to see your friends and family on a map, which is why we’ve added location sharing and check-ins to Google+ for Android (coming soon to iOS). More details about Latitude and check-in changes can be found in our help center.
Google risks alienating early adopters and mainstream users alike with its now common closures of valued services.
