But, Flickr, MySpace, and Digg are basically "has beens" now... Maybe the shiny college crowd of Facebook looked more interesting than MySpace. Digg had a user revolt and they all went to reddit. Flickr? Was it their business model (Yahoo bought them in 2005)? This was written before the iPhone was announced, but Instagram came 5 years later, when did the downturn of Flickr start?

Still, nowadays everything has to be social, so the article isn't wrong.
