Mirroring, & microblogging

Would it be useful to anyone to have a Dreamwidth mirror of my real blog?  There's already a LiveJournal feed you could subscribe to if you wanted. I see yatima and marnanel cross-post from their other blogs to Dreamwidth accounts; do you & your readers find that useful?

By the way, I'm 'denting (microblogging using identi.ca) and syndicating that to Twitter, in case you follow those things.
