In context, it makes a lot of sense for him to do that.
No, it doesn't. Continuing with the charitable interpretation, wearing these two hats at the same time is... difficult. Either he, as an employee of Signal, is genuinely interested in feedback, or he as a participant thinks Fluttershy is all wrong and making shit up because it was perfect for andrewjho (here he, of course, committs the typical mind fallacy, but that's a minor issue at this point).
In December 2015, Robert Cordwell and I cofounded Signal Data Science (website), which we announced on Less Wrong.
Our first cohort has just concluded, and overall went very well. We're planning another one in Berkeley from May 2nd – June 24th. The program is a good fit for people who are both excited to learn how to extract insights from data sets and looking to prepare for industry data science jobs. If you're interested attending the next cohort, we would love to hear from you. You can apply here, or contact us at signaldatascience@gmail.com.
Less Wrong readers might be especially interested by Olivia Schaefer's project, which describes results of doing some natural language processing on the Less Wrong comment corpus, explaining how the words pictured in different colors below are at opposite ends of an axis.
