Not having a 15-year-old sister handy, I'm listening in on the thoughts of the young sister of Medium.com co-founder Josh Miller. Her thoughts and quotes are taken from here, the analysis is mine.
Miller writes that he'd twice been told of the "next big thing" by his sister (let's call her 'Beth' because I'm already tired of writing "John Miller's little sister!") when she said that Snapchat was going to be bigger than Instagram and earlier when she observed to him that Instagram was as popular with her pals as Facebook.
Instagram. 'Beth' observed that all her friends post photos of people rather than "nice pictures." Think about it - what does the average Joe do? He shares snaps of his friends and family; relying on the Pros (and adults) to take the "nice pictures" that we all marvel at. This means there will be many, many more snaps than nice pictures.
Facebook. Speaking of Facebook, 'Beth' and her friends avoid it because "It's addicting, you end up getting lost in it and I don't like that." She also mentioned that she will only visit Facebook when there's nothing left worth looking at on Instagram.
This sounds like an interesting play for the guys at Facebook. Rather than trying to integrate Instagram into Facebook, they should be more interested in targeting the various sub-products at appropriate demographics.
Instant Message. 'Beth' and her friends rarely use IM to talk with each other. "When you go on Facebook Chat the people you don't want to talk to are always the ones who immediately chat with you." Instead they'll use iMessage or Snapchat (there it is again!).
Read on for 'Beth's' opinion of other social media services.
