Replied to Gonna take a communbity to hold that back scratcher: @Tumblr to the #IndieWeb by Greg McVerryGreg McVerry (quickthoughts.jgregorymcverry.com)

Import–needs rock solid LiveJournal-clone and Tumblr support if your site is to serve as an archive. I don’t know if there even is a working WordPress plugin to import from LJ or Dreamwidth. The best-supported Tumblr->WordPress importer is actually better than most standalone Tumblr backup tools…

I made some commits to a project on Github that allows LiveJournal to be imported into WordPress. Would be great to see other projects that import other silo content into WordPress.
