I'm not making any exaggerated claims for blogging changing diplomacy etc. but it is interesting none the less, and certainly a lot more human and constructive than the vile innuendo of the blogs-in-public-life red rag fiasco.

Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare,
The lone and level sands stretch far away.
