My guess is that Snapchat will fade, like MySpace, LiveJournal or AIM.<p>It&#x27;s great for teens and early adults, with tight knit social circles and the undivided attention to look at fast-disappearing posts, but that&#x27;s not much of the population. Lots of people don&#x27;t even understand how it works, while Facebook and Instagram are pretty intuitive.<p>My bet is the current audience will age out of Snapchat, gradually seeing it as something for kids, and the next group of kids will use something else entirely.<p>Of course, I could be wrong--I wouldn&#x27;t have predicted Snapchat would get as big as it has, so more power to them if they can keep it going.
