Good point. I was just thinking about seeing the activities between
the comments, as we're seeing more of now because of the AJAXification
of the bugs page, but lumped together, and de-duped.

Perhaps grouping with a related comment can be considered first, for
activity within a static ~5 minute window following the comment, then
the approximatedate() grouping could be applied.
