I have ZERO interest in Facebook, MySpace or Twitter, and do not even have accounts on any of these. Definitely NOT a good idea to have this so-called "interfacing" between social systems.

So far I have not seen any positive reaction to this announcement from anyone I know. I think if enough folks here express their displeasure to LJ management, that they'll rethink this new "feature". Or at least offer us all the option to opt out if we don't want to participate.
