<p>Adding to other answers, we need to employ tags better. For example: <a href="https://stats.stackexchange.com/questions/182734/what-is-the-difference-between-a-neural-network-and-a-deep-neural-network-and-w">What is the difference between a neural network and a deep neural network, and why do the deep ones work better?</a> does not contain the tag <a href="https://stats.stackexchange.com/questions/tagged/machine-learning" class="post-tag" title="show questions tagged &#39;machine-learning&#39;" rel="tag">machine-learning</a>. It could, and in my opinion, should. The answerers did not receive points toward a <a href="https://stats.stackexchange.com/questions/tagged/machine-learning" class="post-tag" title="show questions tagged &#39;machine-learning&#39;" rel="tag">machine-learning</a> badge answering a question that's is obviously about a part of machine learning.</p>
