After some well-meaning survey spam, I've needed to re-examine my blog comment policy.

So, severely off-topic comments (relative to the post subject) may be Moderated. ( I love euphemisms like "Moderated", when what I really mean is "Annihilated" ).

If you've a non-commercial survey about blogging you'd like to encourage people to do it, this is probably the post entry to do that in, as it talks about blogging and comment policies.
