The reward is when someone replies to your snapchat, it's social validation.
It just feels (to me at least), that this is a problem. Granted before what we consider to be the electronic age of social media, this kind of validation existed -- for example, getting a phone call from a friend would give one a similar level of validation - I have a friend! He/She likes me enough to call me!" - it wasn't something someone expected to happen every ten minutes and it wasn't something that required you to do anything.t
Now that we are all connected, we post, we expect validation that someone has read the nugget we posted. Yay! Friends!
I dunno, just strikes me as something to be leery of..
