To be honest, the social media as a whole is hard to catch up because the whole media can rapidly change every year. In 2012, Pinterest and Instagram have been dominated the social media. In 2013, we all expected Vine is going to get very big.
How can we catch up all of these? There are some general rules and we need to understand what younger people think. Once when we understand what they think, catching up the social media is not too difficult.
