I dunno, we were "social mediaing" back in 2000s sometime, that's when most of the youth started posting pictures of themselves on the internet and using computers+webcams for communicating among ourselves, many of us used our Sony Ericsson (or similar) phones for taking pictures. I think that particular website that started it all, peaked around 2007 sometime, and was shut down by 2010 already, because of lack of activity. Plenty of sites between 2000-2010 that was the predators to modern social media too, some of them literally centered around sharing and commenting on images, kind of like Instagram, but way before.
