The problem is that there is no moderation of content by the administrators. I understand that moderation is time consuming, and therefore expensive. However, the administrators could cultivate a network of regular posters to become joint moderators. I'm sure we could find a nice balance between freedom of speech and reason.
AT ONE POINT, the NVS looked like a MASSOB forum with a constant stream of articles from the likes of Rudolf Okonkwo. Most of these articles were saying the same things and using the same arguments. Also the authors rarely responded to arguments that countered the thrust of their articles. Effectively, they just put the poison out here, and disappeared untill they return with more poison. I simply got bored with it.
To make this medium more effective, every participant needs to be registered, and it needs to be better moderated. However, this is still easily the best serious Nigerian forum around.
