Code review comment for lp:~thumper/launchpad/daily-ajax

@wgrant, @thumper - Theres an odd structure here:

The mixin looks like it could just depend on the Editablewidgetbase protocol; I wouldn't use a mixin at this point, just pull it up to the base class (and pull the self.tag setting up too).

Have a think about this, but don't feel you need to tell me what you choose to do.
