Does anyone out there have any best practices for blog retention? Ie. if you have a publicly facing blog, and the project that was being discussed in the blog is completed, do you delete the blog completely, or do you retain it in some way, and simply remove ability for the public to comment on it? Do you just retain the blog posts alone, or keep any comments with the posts?
I have looked, but can't find anything relating to best practices in this regard.
