In addition, the source code includes templates for hosting these conversions on Google App Engine. Future additions to the project will include support for BlogML and synchronization tools between various services that do not provide an import/export feature but do provide APIs for accessing and modifying blog contents.
Having read with interest about some of the challenges that the folks at Enter Content Here faced when moving from Blogger to WordPress late last year, I'd be interested in seeing how their migration would work with these new tools. It's not often that you see a company offer up tools that make it easier to move off of their platform, but to paraphrase their post, your blog is your data. This, of course, isn't the only way to move your data -- many content management systems offer modules specifically for importing data from other platforms -- but this is the first time that I've seen so many options in one place. It's a bit of a Swiss Army knife approach to content migration, and I think it will be very well received by the blogging and content management communities.
