While listening to the news on the way home, one of the stories was about teenagers, specifically 16-18 year olds ditching Facebook as they find it embarrassing to see their parents either sending them friendship requests, reading their posts or even just seeing them using it.
As a result, 16-18 years are are turning to simpler rival social networks such as Snapchat, Whatsapp and Twitter, even though Facebook is technically better and more integrated. According to the Independent newspaper, Facebook is basically dead and burried by this age group who see it as uncool and is now mainly used by older family and siblings.
It'll be interesting to see how much longer it'll take for it to actually nosedive in popularity overall. At this stage, I'm one of the few people I know that has never had a Facebook account.
