Afaik all reported posts are reviewed. Sometimes a PM is more than enough, do you really want public action every time?

Some threads seem more like chatter than discussion, if that would stop most of the issues we have at the moment would be gone.

These forum guidelines/this policy is common sense but it happens to be hard for some people to not to troll or not to use bad language. These guidelines are written down at many forums I know.

To have post by new members moderated all the time would be a lot of work, instead having people not being able to start new posts in some sections till they have 5/10 posts and only have new threads in those sections (general, community, N900, Fremantle) moderated is a good idea from my pov.

What I notice quiet often lately is complaints about moderators in posts.
Most of the time it is not a moderator cause I would point the guy to the search results (proper links) or merge the thread to the right one right away. Please make moderators aware of such posting by "Reporting" the post and you may also answer the question asked so we could just delete the "search for it" post and close the thread as solved or merge it to the right place.

Are you sure you talk about moderators?
Few days ago I closed a thread cause someone necroed it by hijacking it. I asked to not do so and closed the thread for now but telling that I open it any time when needed for the actual topic. I still think that is the right decision in any case someone hijacks and necros at the same time. In other forums necroism is unwanted but I guess this is not the same here. Answering 3 month old questions is still an answer or a topic that wasn't the least bit interesting might get interesting 3 month after the first post.
