So if you have not heard already, Google has released an app called Ask Friends (note: What's with the Mobius at the end?), in which you can ask your friends random questions to which you will hopefully receive some worthy advice.
Google posted about this on their Official Orkut Blog, while Rahul provides instructions (with pictures) on how to add this feature over on Devil's Workshop.
Perhaps the greatest strength and weakness about this app is its simplicity. It is easy enough that even the non-geek can understand how to use it, although without any extra features people may choose to send out mass scraps, especially now that users can send fancy scraps such as video's images, etc.
If Google allowed users to ask questions via video (perhaps using YouTube's Quick Capture) as well as embedded Google Maps (which would help people out if they were asking for directions) then this feature may find itself to be quite popular.
Note: Speaking of Maps, is it me or is the Orkut Frind Map down?
