\begin{abstract}
Hello Redditors! I'm Elad Yom-Tov, a Principal Researcher at Microsoft
Research. I am a Machine Learning and Information Retrieval researcher,
and for the past few years my work has focused on using Internet data to
study our health. Internet data are all those things that we create
while browsing the web: posts on Facebook and Twitter, queries on Google
and Bing, blogs, and other content. These data can teach us about
aspects of medicine that are hard to learn about in other ways. A few
examples include measuring the effect of mainstream media on the
development of eating disorders, estimating the effectiveness of flu
vaccines, detecting new side effects of medical drugs, and discovering
how visiting a dating site can lead to catching an STD. My book on these
topics, Crowdsourced Health: How What You Do on the Internet Will
Improve Medicine (MIT Press) was published earlier this year. AMA,
including questions you are interested in, and perhaps we can research
together! I will be back at 11 am EDT (8 am PDT) to answer your
questions, AMA! Edit: Folks, thank you for your being interested in this
work, and for your questions. It was a real pleasure discussing my work
with you. I'll check in later to see if there are additional questions.%
