A bit early, (or a lot late ) but I love this post. Beverage warnings apply:

In a world where many blogs and websites are shutting down comment threads, I think we all need the occasional reminder of why we permit comments. Sure, you often learn something new from other people’s inputs, and sometimes get corrected when you step beyond the limits of your actual knowledge-base too far. But sometimes you read a comment that’s so brilliant, you just have to look up the commenter’s email, and beg them for permission to repost their work of art. This was one of those times.
