@ thisiscarlosm , this is interesting. I think that not only are there probably folks on Snapchat not using any other social media but there are probably folks on Instagram, Facebook and Twitter that only use those exclusively. I would be interested to know the numbers and age groups for each of these sub-groups. I use Facebook and Steemit primarily and only use Twitter every now and them. I just started using Instagram. Sorry Snapchat...I'm already too busy to get involved with you. :)
