I am a fan of Angry Robot
A little while ago, I posted about how Angry Robot books was trying to build a sense of community with its readers by offering package discounts and selling lifestyle products. They’ve taken this a step further by encouraging readers to write fan fiction of selected Angry Robot books — and by promising to publish the best fan fiction in anthologies and pay the creators. Pay the creators of the fan fiction.
Please take note, other publishers. This is how you keep your fans happy and make a little extra money while doing so.
