A Possible Solution?
Just found out that WordPress 2.0 is scheduled to debut on December 26. And while most of the changes are under the hood, Asymptomatic has a posting with a list of some of the new features.
The one that caught my eye though was
New Import System - The new import system leverages the abstraction done at the data layer, so that import routines can call simple functions to convert posts from other blogging tools instead of a huge complicated series of queries. Importers are also available directly from the admin, so no special process need be taken to employ them.
I won’t know for sure until I download the new version and try, but I’m hoping this will make my blog consolidation easier.
