I wouldn't assume that Google's algorithm is "broken." Relying entirely on on-site optimization is a poor strategy that will continue to yield undesirable results.
Off-site optimization will protect you from Panda and help you bounce back faster when you are affected, as well as improve your existing rankings.
You may not want to manage social media profiles, but you should definitely get links from some reputable and relevant external resources.
