 I use tags for agenda filtering (primarily for GTD contexts, see below). Each tag here starts with a symbol to define its group (note, only the special chars "_", "@", "#", and "%" seem to be allowed; anything else will do weird things in the hotkey prompt). Some groups are mutually exclusive. By convention, any tag not part of these groups is ALLCAPS (not very common) and set at the file level.
