You can also watch your friends' Stories anywhere in the app by tapping and holding on their usernames, which is convenient but unrelated. The share-thru-Snapchat might be a new avenue for referral traffic, TechCrunch points out, as the old method required users to copy and paste URLs. For the record, Android already had this feature, and it's getting the 'Ghost Mode' later today or tomorrow.
Ghost Mode is a nice addition for folks who previously forgot they'd permanently toggled off location sharing. Given that many users don't even realize that's part of Snapchat, given that it's hidden behind the in-app camera screen and accessible via pinching out, this might bring the 'discover nearby' feature some needed visibility.
