Okay, so I probably can't answer all the comments related to the Facebook/Twitter fiasco, so post instead!
I do not have Facebook, never will. Way too stalkerish for me. I do, however, have Twitter, which is under the same name as here. If you feel compelled to do the crosspost comment thing, I have no objections. On PUBLIC posts, of course. If you break the friends lock sanctity, we're going to have issues. On the other hand, I think this has been an absolutely stupid move on LJ's part, and they seriously need to give everyone the option of disabling those stupid crosspost buttons, and/or modify them based on post security settings. Do these people not do the simplest research before implementing their kooky ideas?
