mmm this could be good. Trying out the 'publish-to-all' Firefox extension ScribeFire.
Write to as many blogs as you care via the Firefox window you are in.
Only issue at present is i can't find the spell checker, which with my abilities is quite an issue.
(after test) Whoooa. look below! some weird clash going on with the 'copy and paste' function. Either that or i'm being a real plonker. Still a neat idea to streamline blogging.
