As far as building public awareness of the dangers of homeopathy, I have tried to start by educating people that they should not be promoting The Huffington Post in any way. HuffPo is no friend to the reality-based community and has been one of the biggest proponents of homeopathy and other dangerous forms of woo.
This has been a real challenge, and I continue to see many atheists link to HuffPo, retweet their articles, etc. For those of us who are bothered by homeopathy, we can do better. Here are some more examples of why we need to let go of HuffPo.
