Promoting Indie Authors

I only have time for a single social media outlet, Twitter, and on that outlet there is a lot of talk about promoting indie authors. There are a lot of what I would call ad-tweets, of either the author or their publicist sending a cover photo and a link. Fewer tweets by individuals calling on people to "do the right thing" and support indie authors by "buying their work, reading their work, reviewing their work". And then there are the numerous tweets of support back and forth between writers which are lovely to get and give but not material in the sense of the above.
I think (actually know) that there is a lot of talent toiling without much support, especially when compared to the handful of authors who get a big-name publisher to support them. I heard that you need 50 reviews before Amazon pays any attention to you. I've tried with my circle of friends and the Twitterverse. A lot of hard work for 3, 8, 12 reviews. Still far short of the 50.
So......
I propose a somewhat unconventional giveaway. Each week (life permitting) I will give away up to $10 worth of Kindle books (I'll shoot for 4 different titles each week). You get a chance at the books by retweeting the initial post for the week with the title or author you'd like to win AND a title or author you'd like to see next week. The caveat here is the titles need to have less than 50 reviews on Amazon. Also, no self-promotion.
In addition, if you post a review here, as a comment to the current giveaway post, of any of the books in any of the past five giveaways (I know, it will be harder at first!), you will get an extra entry in the current giveaway.
Finally, to kick this off, please post a comment to this post with any author/title you'd like to see in the inaugural giveaway. 
Happy reading. Reviewing. And, for the authors, hopefully selling!
