I agree that duplication is not necessarily bad, it just makes it a lot harder to browse the module section on <a href="http://drupal.org">drupal.org</a> to find relevant content, and this is what is really wasting a lot of time for users and developers. <br>
<br>It is my impression that the current "module categories" taxonomy is not really helpful because it has become too coarse to categorize the 2000+ modules that are out there, and a quick informal survey of my co-workers showed that others feel the same about this. Many of these module categories have a couple hundred modules, and their listing spans more pages than the average user is willing to read in order to find what they want. <br>
<br>Would it be possible to simply turn this taxonomy into a free-tagging field, or add a separate free-tagging taxonomy? We would then have terms that can categorize modules much more specifically, but more importantly we would have a way to link similar modules together.<br>
