Should I be experiencing FOMO over Snapchat? Is Snapchat one of those things you only get into if all of your friends are doing it? (like, say heroin for example)
There is nothing wrong with trying out Snapchat. Download the app.
As far as I know, there is no people discovery on Snapchat. To find people to add (so you can receive their snaps – or video messages), go on Instagram and check out user profiles. Snapchat users post their Snapchat usernames everywhere.
Familiarize yourself with the UI. It is quite confusing until you have a mental image of how the screens are linked so you know where you can swipe in which direction to get to the next screen.
From what I can see, Snapchat is dominated by teenagers. Everyone has an account, even if they don’t post, just to watch other people’s videos. The stuff is very mundane and gets boring fast if you are not actually friends with the people who post. There is a lot of posing and trying to look pretty. After a few weeks I deleted the app.
