There was a stupid bug which caused archives to sometimes not be updated when a new post was added to a post chain. That bug has been squashed. All archive pages update properly when links are added to a post chain.
Post Chaining is maturing. At Eugene Volokh's request I added a bulk post chain forging page, which should make creating post chains of content that wasn't originally chained together much easier. I also added some documentation, though it could certainly use some improvement — it's really as much an attempt to get people to use it as a description of what post chaining is and what it's used for.
I'm really excited by post chaining, though. I've spent too much time jumping into the middle of discussions by following Instapundit's links only to wonder what the person wrote afterwards but not being inclined to read their entire front page to find out. I really think that post chaining will improve the usefulness of the blogosphere if its use takes off — while frequent new material is one of the great strengths of the blogosphere, it's also a weakness in that it can be difficult to keep up. Post Chaining helps to alleviate that problem without weakening the strength of constant posting and instant updates.
