I also spent a great deal of time dinking around with my shiny new Dreamwidth layout. (Peanut gallery: What's Dreamwidth, Uncle G-Funk?) It's based on a fork of Livejournal's code, and here's why I jumped there.
You may have noticed that Livejournal's comment page design has shat the bed. Massive customer outcry has had little effect, and signs point to worse interface mangling in the future. Between LJ higher-ups' disdain for its userbase and Dreamwidth's reputation for respecting its own, I figured it was about time to start mirroring. Until the end of the year, you can sign up free - no invite code required. In the future, I should have some invites to hand out. I'm not entirely sure how that works.
I will continue to cross-post, so feel free to stay with LJ if you prefer it. Just extending the offer is all.
