Path hasn't held the same grip on social networkers as Facebook or Twitter, in part because it's almost too social -- you can't really control which friends (or friends of friends) see a post. The solution in Path 3.0? Recreate your Trapper Keeper from grade school, apparently. Along with introducing a much-appreciated private messaging system that lets two or more friends share text, maps, media and voice messages, the update lets us slap expressive stickers into the conversation when a basic emoticon just won't do. Of course, that's also how Path hopes to get a few extra bucks: two sticker packs come free, while others lurk in the same shop as custom photo filters. If you just have to tell buddies that Stacey was soooooo gross in chemistry class, you can get Path 3.0 today on iOS, and shortly on Android.
