Compare it to Twitter limiting your communication to 140 characters. Or Instagram limiting your posts to photos (as far as I know; never used it). Or Vine limiting you even more than Instagram. Or Tinder limiting you to swipes (compared to pretty much every other &#x27;dating&#x27; app out there).<p>In all cases the limitation is rather arbitrary, and yet one of the primary defining aspects of each product. I don&#x27;t think it&#x27;s a stretch at all that the ephemeral nature of Snapchat is its main offering. I kind of wish more of my friends would use Snapchat, because I&#x27;m not always happy with the idea that everything I ever said to a friend via Facebook is stored and can be read and searched by them. And by Facebook.
