I think we should have formal "Bug squash wednesdays"  (or pick another
day). By this I mean that the core reviewers will focus their attention
on just reviews that are related to bug fixing. They will also try to
work on bugs if they have time and encourage everyone else involved in
Nova todo the same. We'd have a team of people in the Nova IRC channel
to publicise & co-ordinate bug squashing, perhaps  with a list of top
20 bugs we want to attack this week. I wouldn't focus just on gate bugs
here since many a pretty darn hard & so would put off many people. Have
a mix of bugs of varying difficulties to point people to. Make this a
regular fortnightly or even weekly event which we publicise in advance
on mailing lists, etc.

Regards,
Daniel
