Since I last posted on this issue, we now have "keywords" that solve
+many of the issues of description and status whiteboard keywords. We
+have seen a migration towards keywords, but there is still further to
+go.
+
+Description ( + Status Whiteboard ) Keywords
+--------------------------------------------
+
+Some description keywords remain. I'd like to hear what reasons, other
+than time, there are for these staying as they are. I'm suspecting many
+are not really being used. Hopefully we can totally remove these
+eventually.
+
+Tracking Bugs
+-------------
+
+When I suggested keywords, I did so to get rid of tracking bugs too,
+though we've had less success on that front.
+
+There are many disadvantages to tracking bugs.
+
+- They can pollute bugs counts, and you must make sure you exclude
+them. I believe the meta keyword might be used for this purpose.
+- They have an assignee but there is nothing to fix, and that person can
+get whined at by Bugzilla.
+- It would be better to craft your own "dependency tree" rather than
+rely on a fixed hierachy in the bug system.
+- In creating a nice little hierachy, many bugs duplicate information
+that should be available in other ways, eg
+"http://bugzilla.mozilla.org/show_bug.cgi?id=12833" which is
+about beta 1 networking issues. These could fall behind the actual
+data. What tracking bugs are good for, ad hoc lists, is what keywords
+are better for.
+- An automatically generated dependency structure between one "tracking
+bug" and another would be better than a manual one, since it gives exact
+rather than manually set up classifications.
+
+Probably the only feature preventing tracking bugs being replaced is the
+dependency tree. The quintessential tracking bug seems to be bug #7229
+"chofmann's watch list", which probably has about a couple of hundred
+bugs at various levels, which allows a nice visualisation.
+
+Before keywords can replace tracking bugs better visualisation is going
+to be required. General summary reports and dependency forests of a bug
+list ("http://bugzilla.mozilla.org/show_bug.cgi?id=12992") could both
+help, but neither solves the problem totally. Perhaps keywords within
+keywords would help here. In any case, I'm still thinking about this
+one.
+
+Some tracking bugs could definitely be turned into keywords immediately
+though, and I'll point the finger at
+"http://bugzilla.mozilla.org/show_bug.cgi?id=7954" here since that's
+what came to mind first.
