Completely agree, and I'd also argue that social media's worth varies quite widely based on a brand's current market penetration. Pepsi and Coke are so ingrained in our consciousness due to other ad buys that their social media outreach may be automatically be resented as "corporation is invading my Facebook".
But for smaller companies, at the very least, social media is a much frictionless way of disseminating updates and news, compared to email signups and expecting people to go to your company blog. And upstart companies may (initially) be seen in a more positive light for their seemingly underground/non-pretentious way of communicating to their fans/followers. I'd say that's hardly "worthless"
