The Calgary Herald recently decided to take an excursion into allowing comment on their articles to appear on their web site. This lasted no more than a month. Now, if you criticize the Government by citing oil royalty, spending or mismanagement in general the comment stays up at best for an hour or so but more often does not make it past the moderator. Never to see publication.
Likewise the Edmonton Journal regular addition. The digital publication seems to be more forgiving.
