One thing both Facebook and G+ are missing is the ability to create targeted messages based on attributes. For instance, I will be traveling to Denver in August, and I'd love to target a query to "people living in Denver" without specifically adding Aaron Bailey (like I just did). Facebook Ads lets you target ads to attributes- why can't I do the same in my wall posts, Notes, messages, etc? That would make having a LOT of friends actually useful.
So I just went to a friend's profile to let him know he's the first to make it into 3 circles. but for the life of me I couldn't find a "Message" button. Seems like a miss to have to pop out to Gmail to send them a note... am I missing something?
