This is just the deletionists vs. inclusionists debate from Wikipedia in the 90s/00s. The deletionists are still winning and the deletionists are still wrong.

This is just the deletionists vs. inclusionists debate from Wikipedia in the 90s/00s. The deletionists are still winning and the deletionists are still wrong. The result isn't a higher-quality StackOverflow or Wikipedia, it's a narrower StackOverflow or Wikipedia. And with the subject matter StackOverflow covers, narrower actually means lower quality, because answers fall out of date quickly, and new problems arise quickly. My most recent question on StackOverflow was about Valgrind on MacOS, and it was deleted quickly. I was pointed to a bunch of questions, which I had already looked at, which had only answers from before Apple made some changes that broke Valgrind. Last I checked, if you're running an up-to-date version of MacOS, everything StackOverflow has to say about Valgrind is useless. Quality? I think not.
