I've been pondering what to do with this site. It needs to be refreshed. But I don't want to do anything stupid, as I'm sure to, and accidentally delete the last four years of my life completely.

Do I start out fresh, from scratch? Or do I somehow figure out the complexities of migrating my content to a new version of MT or some such application?

I took the fresh approach last time. Did you know that I had a blog before this one? I love that the web archives my life for me. Embarrassing as it may be, the documentation of my ramblings lives on for eternity.
