I totally agree with you. I'm mostly trying to criticize the disproportional amount of press for a very preliminary and inconclusive study. The treatment of science in the media can have very real effects on people's behavior, but also in the way that they view science. If large groups of people start practicing something that doesn't work, or worse, has negative effects, then when the science seems to change its mind later on, that breeds distrust in the scientific community. How can science lead to truth if it is contradicting itself all the time?

Also, public hype influences where funding goes. Maybe this is a promising route, and definitely should be studied further, but maybe some other more promising research is not being funded because of it.

You seem knowledgeable about the fecal microbiota transplantation, but for other readers for a short an informative review article of fecal transplantation and its history and promise, take a look at "An overview of fecal microbiota transplantation: techniques, indications, and outcomes." The focus is on clinical practice, but it gives you a good idea of what is involved and what it has been used for. It's a few years old now, so the field has evolved a bit.
