Yeah, among other biases. "Voluntary response data are useless." I've also tried posting it on /r/datascience but it appears to have not showed up in the sub, maybe because my Reddit account is too new. Do you have suggestions for other DS communities where I could solicit responses?
Hacker News maybe? Not exactly specific to data scientists, but I believe there's a significant number of data scientists lurking around. Same biases, but it seems you're aware of those.
