Google announced an update to Google Maps for Android. The big update is a new "Places" feature that allows you to find places near you via Google Maps.
Places is a separate "App" that can be found self installed after you update your current Google Maps app on your Android device.
You click on places and it asks you what places near you do you want to find. Such as restaurants, coffee, bars, hotels, attractions, ATMs, gas stations and more. When you click on a place, you can pretty much check into the place via Google Buzz or read about it, get driving directions and so on.
This reminds me a lot of Foursquare, which let's you check into places. The only main difference is that you don't get badges for checking in. You do however get tips.
