Marketing for Artists and Creatives

No I don’t have any special insights on marketing for creatives and artists. I’m not particularly good at marketing. I have a Facebook page with 50-some followers, a Twitter account with 252 followers, and a Tumblr with 23 followers. My Etsy shop has 33 followers,and this blog the readership of which is unknown. None of this translates into more than selling one print a month or less. I’d love to find some current information, how-tos, videos, instructionals etc on marketing art with a specific focus on low cost social media that doesn’t annoy the crap out of everyone you know. Anyone know of any resources that fit this description? If I find any, I’ll post it in the comments.
