Ask HN: Best resource for learning social media marketing?

I, like many hackers, I think, am not a social-media-diva. But I've got a product and a shoe-string budget, so I feel strongly I should learn to use the resources.

I only recently even realized there was any cleverness to any of the techniques. Previously I had rather thought it was (a)make more friends on facebook (b)get some twitter followers -easier said than done without huge time investment (c) ask them to "Like", "Review", etc.

I've learned a few more things, but the blogs and resources are disparate, so I'm hoping there is a "Seth Godin of social"
