Note here that currentLocation has disappeared from the People API. One year on from the death of Latitude and apparently location is being dropped. AFAIK, there’s no longer any way of setting a profile current location since Checkin doesn’t set it and I can’t find any way of changing my profile from “lives in” to “currently in”. My guess is that location history is going to disappear as well.
And yes, I hear you about the Platform API bug tracker. It’s a black hole. Try sorting on most starred, there are 100 or so with more than 2 stars most of which are dormant and have been for more than a year. See Also,
My plea from the beginning of the year for Google Staffers to do some pruning and cleaning of the bug tracker database.
