There's a plugin I use on my wordpress blog (http://blog.scatmania.org/) (LJ crosspost) to post copies of everything I write to my LiveJournal account (for my friends who prefer to use LiveJournal's "friends page" to RSS, the heathens). If you're considering migrating your blog in a similar way, you might want to look into it.

I'm a big fan of saved sessions and non-scrolling tabs, too. I finally found a set of plugins for Firefox that make it behave like Opera, which pleased me immensely (I'm a big fan of Opera), because there are other plugins (Web Developer, Tamper Data, Google Reader Notifier, Color Picker, MeasureIt, etc.) that I use daily and that Opera just doesn't do.
