Mark's response was strong

You're ignoring Mark's point.  I think he was right to push back a little.

If the automatic first response of developers is "go bisect it!" then that doesn't save time
for anybody.  Most bugs don't need a full bisection and many bugs won't bisect well well (as
noted by the article).

Both parties in this discussion had excellent points.  Ideally devs will have to compromise a
little by considering the bug report for 30 sec to reduce wild goose chases and making users
feel like they're getting the runaround.  Users will have to compromise a little more because
they scale.

In an ideal world.  :)
