Perhaps the lack of reviews is due to the minimal audience available on this message board or is because of the excessive non cruise related posts that appear as well as the numerous "seeking companion" posts that seem to dwarf the newest posts daily !
In the end, the audience just seems to be "slack" on providing reviews of their cruises compared to other sites and "strong" in off topic subjects and friendly chatter.
Just my observations since being a member of CM for the past years
I feel confident I will be flamed by some for those comments and told to not read the topics if they do not interest me (the standard reply if you say something negative here !), but they are JMHO !
