However, a robots.txt rule could also do the job you asked about -- but you'd need to remember to update it every year. Assuming your blog is at the root of your domain:
User-agent: *
Disallow: /2006/
Disallow: /2007/
[webmasterworld.com...]

Question: Where is that post now getting its link juice from? Doesn't it simply become an orphaned url?
