Unfortunately, there's been a lot of comment spam recently, so as a temporary measure, I'm moderating comments on all older posts. It's not an ideal solution, but the best I can do quickly. Once Sail Hebrides' Hebridean Maritime Festival (more to follow...) is out of the way, I'll find a more permanent, user friendly solution.

Update: I've changed the moderation plugin (from NP_CommentControl to NP_Moderate, in case you were interested) so now you should be notified that any comments submitted will be queued for moderation, rather than just appearing to vanish into the nothingness.
