This has a lot to say on the subject and most of the comment is from the 
sidux
maintainers:-

These guys know more about managing Debian sid than I''ll ever know.

Neil: If I have the time I'll try to find the Debian quote vis-a-vis 
apt-get and sid.
If I'm correct it was made fairly recently by a Debian developer in answer
to a question regarding Debian sid. It's also worth remembering that Debian
will not recommend anything other than stable for day to day use and most
comment is made in light of this.
