This is what we used to do when we (I) annotated all the changes to produce /n/sources/extra/changes. But it was far too much work to do the annotations and not enough people cared, so we stopped that particular experiment.
There are 75 people subscribed to the plan9changes[1] mailing list, is that not enough people that care? uriel [1] http://groups.google.com/group/plan9changes
