<p>Recently, I posted two questions about Crowdsourcing on CV. The first <a href="https://stats.stackexchange.com/questions/248129/general-reference-for-crowdsourcing">one</a> asking for a general reference got upvoted, while the <a href="https://stats.stackexchange.com/questions/247648/references-for-good-practice-in-crowdsourcing">second</a> specifically asking for a more specific reference concerning different experimental design decisions got closed as off-topic. However, quite a few commented that it appears to be on topic to them. </p>

<p>For me this is quite frustrating. Is crowdsourcing on topic or not? I am pretty sure it should be, because it becomes more and more important for ML, on ML conferences there are numerous papers on the topic, and the "experiment-design" tag on CV has about 800 questions. </p>

<p>If you disagree, please give solid reasons. If not, please consider re-opening my second thread.</p>
