<p>I think general tags are not very helpful especially since we can only have 5 tags per question. In addition, searching for questions via a combination of tags seems an additional step that is not user friendly.</p>

<p>Having said that, creating a semantic network among tags is a good idea but this may need new functionality. I am not sure if changing how we tag (general instead of specific) is the best way to create a semantic web.</p>
