One thing can't be changed, when you make a post in a blog - the original "adress name" of that post:
http://www.lordtobyharris.org.uk/the-prime-ministers-instruction-to-the-metropolitan-police-to-review-madeleine-mccanns-death-is-in-breach-of-the-draft-protocol-that-is-supposed-to-protect-the-operational-independence-of-the-poli/
People can edit the content, but if they don't delet the post, the original first phrases are still there, in the post internet adress name. "Netiquete" demands that you show clearly to your readers that you corrected or changed the content of a post. Lord Toby Harris forget that?
