I have been working on a new LiveJournal client written in PHP called ljread. It now supports multiple accounts, moods, music, preformatted html, and a bunch of other features. It has a few bugs still, and the ability to post is still not implemented. I have a lot of planned features too, such as caching of data in a mysql database so your friends don't tax the livejournal servers. Anyhow, the developmental version of this script can be viewed here. The stable version which is available for download can be viewed here and downloaded here.
