Why can I see where someone is posting a facebook message from?

I was talking with someone online using facebook messenger and noticed an icon a bubble I hadn't seen before. I clicked on it and it took me to a map and to a street name and suburb where they are posting from. I have never seen this before. Could they use it to find out my address? Or is it just they way their computer is. The map was through Bing! Anyone else seen or heard of this?

Yes, you can turn off the GPS location on your phone in your facebook settings so that people don't know where you're posting/messaging from. If you're messaging from a computer then they shouldn't be able to see your location. It's just a facebook mobile thing.
