I have started the process of back-porting the posts of the previous version by exporting the posts from the WordPress database (and running them through a script). All those posts are in the repo.
I will not back-port all the posts: most of them are available on my blog anyway. I will back-port the ones about Rubicon that were not simply the commit messages for the project.
UPDATE: I have finished triaging the posts from the previous version of the site. There are three posts that will re-appear on this site with their original dates and contents. The other posts either live on my blog or remain available in “raw” format in the repo.
