Google is reportedly testing a new service called Google Mine internally at the company. It appears to be an app that lets you keep track of the things you have, and the things you want, and share them with friends.

Alex Chitu, tipped by Florian K, shares a screenshot, and quite a few details.

As described in the app’s authorization box (pictured), “Google Mine lets you share your belongings with your friends and keep up to date with what your friends are sharing. It enables you to control which of your Google+ Circles you share an item with. It also lets you rate and review the items, upload photos of them and share updates on the Google+ Stream where your friends get to see and comment on them.”

This seems like a pretty good way for Google to get all kinds of data about people, in terms of specific merchandise, if enough people use it. It could be a treasure trove for advertisers.

According to the info Chitu shares, the product lets you organize the things you own, the things you use, the things you “wish for” and more. This includes gadgets, clothes, electronics, DVDs, cars, bikes, etc. You can see where advertisers might be interested.

The info indicates that you can use Google Mine to catalog belongings and track and review them. You can control who sees what, track conversations, send request to borrow items, share stuff you want, get recommendations, and share stuff you’re giving away.

Google reportedly already has an Android app up in its internal version fo Google Play.

It should be noted that just because Google is using something internally does not necessarily mean it will become available to the masses. The borrowing-related features, in fact, make a great deal of sense at the internal level, in that people who work together often see each other, and could easily exchange items at work and whatnot.

That doesn’t mean this couldn’t work as a public app, however, and that kind of data has to be attractive for the reasons mentioned. It will be interesting to see if this becomes a Google product that everyone can use.
