I think the issue here is that you're comparing RSS with Social Media only as a consumer. But in Social Media you're also producing content and interacting with other users, and also watching interactions between users, that's for me a big difference between RSS and Social Media too.
RSS for me it's like reading the news paper, while Social Media would be to go to a bar with some friends and talk about the news/hot topic of the moment. They cover different needs.
