I see some questions tagged as "project-management". Since that's the subject of the entire site isn't this tag somewhat redundant?
There should be a rule that the tagname cannot match the name of the site. For instance, Programmers Stack Exchange shouldn't have a Programmers tag. Area 51 shouldn't have an Area 51 tag. Cooking shouldn't have a Cooking tag. Automotive shouldn't have an Automotive tag.
The idea is that tags should represent a component of project management or a component of the site topic, and a subject cannot be a component of itself.
I asked essentially the exact same question on the meta page for the sister Stack Exchange site for Board and Card Games.
Although we had a lot of discussion in the comments below, we were ultimately barking up the wrong tree. The right way to deal with this was described by a SE guru in another answer: basically for this site, the project-management tag should be blacklisted. I assume Jeff Atwood can fix this for us here just like he did over at B&CG.
