1) Download the Delicious Blog Rescue addon for Firefox.
1A) If it complains that it's not compatible with your version of Firefox then you'll also need the Firefox Addon Compatability Reporter, which allows you to turn back on addons that are disabled for not officially supporting the right version.
2) Set it up like so:
replacing the delicious Account username with your own, the LJ or DW username with your own, entering your own passwords for each, and replacing the XML-RPC URL with the lj.php version if you're posting to LJ rather than DW. Oh, and changing the time to the one you normally post at, if you normally post at a different time to me.
3) Click "Make Blog Post"
I'll be doing this in the evening until I get my alternative up and running properly, so the midday post will become an evening post.
Oh - important thing. For some reason the tool produces excess divs in the HTML. You'll need to find all the instances of <div class="delicious-extended"/> and remove them, or you will _really_ fuck up people's friends pages. If anyone can explain to me why empty divs would do this then I would be most appreciative.
