Coming in the near future (probably with the launch of MvBlog 1.5), I will have a nicely filled category Historical Posts.
Using the WayBackMachine, I am manually importing some of my posts saved on older blogs. Because I thought I had lost almost all of my entries, I used the WayBackMachine to see what was left. Almost all of my posts, and even some images have been saved for posterity :)
UPDATED – Historical Posts is now active!
