I saw a little snippet in lj_nifty about the new Semagic Client allowing you to sync your LJ, in other words, to download it to your HD, then keep it current with the online version. You can edit entries, post, reply, etc. and the interface also has the LJ specific tags and bold, underline, italic tags, etc., so you just click on them and type your info. No more adding the HTML manually. It also has an icon for your systray that lets you know when you get replies and when your friends page gets additional entries. All-in-all, I like it. I like it a lot! I haven't used any other clients and have, to this point, done all my journal entries directly through the web client. Not any more. Give it a try!
Here's a link to the LJ Journal for this client with details and a link to download. If you d/l it, and you like it, tell me about it.
UPDATE: Seems this client was creating a drain on LJ so they have asked that the history sync portion not be used, but have promised to make a journal downloading feature a priority to stop the Semagic problem from recurring.
