What is the thing you send on Snapchat?
Since time immemorial (or fall 2012), I would’ve answered: a snap. The first syllable of the service’s name—denoting a picture-with-a-half-life—was Snapchat’s unambiguous atomic unit, its clear medium of exchange. “I saw that snap you sent me.” “Did you get his snap last night?” “She sends such good snaps.”
Snap especially leant itself to superb portmanteau: Snaps that featured a canine were dogsnaps; snaps from the male parent of newborns were dadsnaps. We might bicker over whether the word should be capitalized, but its reign was clear. On Snapchat, you sent snaps.
Then, last October, Snapchat announced a new feature, Stories. Snaps could now be strung together into public slideshows, visible to all one’s friends. Snapchat blandly instructed us what to call this kind of communication—stories, duh—even though the best use of the medium didn’t seem to be narrative so much as braggartly; “stories” were where you sent snaps that you wanted everyone to see.
And now we have—well, what, exactly? Yesterday, the company updated its eponymous service with the ability to send text and pictures to other users. It also lets you video chat with friends when both of you are simultaneously online. Also, you can now save certain text messages from friends by clicking on them (and you can still, of course, screenshot anything).
