Why impossible? When you submit URL: NH offers few general categories in a mandatory field. OP chooses most suitable. Homepage provides filters: ALL / CAT1 / CAT2 / CAT3. Nothing drastically changes, but helps with content consumptions significantly. For example, I might be interested only in hardware stories, so I'll click on the HARDWARE cat/tag whatever.
