awesome! i’ve been working on a similar project for a while. it imports your posts and other content from facebook, twitter, etc. into blogging platforms like wordpress, tumblr, and blogger. it doesn’t dive as deeply into wordpress in particular, but trades that for breadth across the other destination platforms.
it uses another project, https://github.com/snarfed/activitystreams-unofficial , to translate the data from each source platform to a common format (ActivityStreams), before converting it again to each destination format.
i’m glad to see more people working on these kinds of IndieWeb projects!
