-I use tags for agenda filtering. Very fast and simple.
-Each tag here starts with a symbol to define its group. Some groups are mutually exclusive, and each group has a different color.
-Any tag that is not part of these groups (eg some filetags in the few cases I use those) is easy to distinguish as it has the default tag color and is all caps.

 There are several types of tags I use:
 - location: a GTD contexts; these start with "@"
 - tools: also a GTD contexts; these start with "#"
 - attribute: useful flags for filtering; these start with "%"
 - life areas: key areas of life which define priorities and goals; these start with "_"
+
+NOTE: only these special chars; others make the tag chooser do weird things with the hotkey
