They're actually interesting, and worth checking out. Also, they fill in a few tiny moments and scenes and some back story on characters that haven't been totally introduced. I spent a good hour or so reading through them all.
Oh, and if you're willing to use their flash player to watch them, some of the scenes are clickable and give you production stills and things as little easter eggs.
Then there's this link that goes to this cool blog set up by the character Hana, the one who can tap into any wireless communication. On it there's scuttle butt about the elections and other stuff.
Maybe you all already knew this, maybe not, but I thought I'd share!
