Technical hoop-de-doo

My ambition is to be able to publish blog posts here and at Livejournal simultaneously, so I can start attracting eyeballs here but not deprive my longtime readers over there. It should be a fairly simple matter to do it by e-mail without the rigmarole of manually double-posting, but like most simple matters in the programming world, I need to go find the procedural needle in the Matrix haystack first. Trial and error is underway.
