how to check in at home using latitude in google map

This is present in google map 5.3 and above in android.To check in at home using latitude,you need to do

1. Check in from Latitude and tap “Home - Tap to set your location” at the bottom of the nearby places list if you don’t have one yet.
2. Use the estimated current address or enter in your home address yourself.
3. Once you’ve checked in at home once, “Home” will appear at the top of the list when you’re checking in near there.

Its totally an opt-in service and the set location "home" is not searchable.Though one can share it with friends just like other check-ins.This service is particularly useful now because of the availability of "location history dashboard" in phones.It could help you to see how much time you are spending at home or work or in leisure!!!!!!!!!
