An interesting approach to managing comments by editor Barton Cromeens at the Abilene Reporter-News: Get the commenting community involved and work hard at making comments add value:

The First Amendment is under attack.

Ironically, the attacker is a free press that is frustrated with a
changing media landscape and that is reacting poorly to a populace that
is equally, if not more, frustrated by unmitigated, unrestrained
vitriolic online commentary.

Readers and communities are fed up. Demands and threats are being made.

The most common demand – put an end to anonymous commentary. The most
common threats – litigation, withdrawal of financial support,
discontinuation of readership.
