Tags are not a suitable replacement. People go to General to browse, not to look for specific categories of topics. So basing General on a system that just dumps all the garbage there with the intention that people will use tags is a completely incorrect way of thinking about it. Instead it makes General more and more uninviting and frustrating. The tag idea does have its own usefulness, but it does not replace having subforums to collect topics to keep General a cleaner and inviting place to visit. As the Spectrum General fills up with more random garbage, there is less and less incentive to migrate over from the old forums, which handle this much better.
