> Respondents were recruited primarily through channels owned by Stack Overflow. The top sources of respondents were onsite messaging, blog posts, email/newsletter subscribers, banner ads, and social media posts. Since respondents were recruited in this way, highly-engaged users on Stack Overflow were more likely to notice the prompts to take the survey over the duration of the collection promotion. We also recruited respondents via a Reddit ad campaign, this accounted for < 2% of total responses.
