I will post more about it later, but the short version is this. I have moved my main blog (as hosted on my own domain) from Blogger to WordPress. With a few plugins, and some adapting of some of the code to my own requirements, not only can I post on my main blog, and see the posts appear immediately on LiveJournal, but I can import comments back from LiveJournal onto my main blog, essentially consolidating the two.
The one thing I haven’t licked is mirroring comments made on my main blog to the version on LiveJournal, but that is less of a concern for me at the moment.
Note that http://blog.filklore.com/ is currently awaiting zone changes, so isn’t working at the moment – it should be fine again sometime in the next 24 hours. However, http://www.filklore.com/ is up and running.
