Of course there is drivel on social media sites, just as there is in newspapers, on television and (dare I say it) on forums like this. They key to it is finding the content you are interested in, which isn't hard, and filtering out the drivel. Once that's done you have access to information, news, and (for a business) the means to manage your brand and engage with your customers.
At the last count Fernando Alonso has 591,226 followers on Twitter and his team have 277,142. That's a lot of fans, and customers, which Fernando and Ferrari have direct access to and who are interested in their brand.
