social networking sites

      Well for starters they are called "social" sites so I wouldn't necessarily call information private and public.  Because lets face it things you put on the internet become published and public, though certain things can be deemed classified, confidential and require access via password or some kind of limited day pass that you have to pay for etc. In other words I think that there are varying degrees of public information.
but my question is, what kind of message is it sending that we tell young kids not to be on these sites then have them join for classroom purposes like to get their daily assignments? in a way doesn't this subject them to improper usage of SNS potentially subjecting them to online bullying.. but then again maybe teachers use more sites like blackboard or something which allows young students to have the same experience but in a "safer" environment that is only for their class.

it's nice that Facebook has privacy settings and allows you to customize them to suit your needs and uses but why is it that every time Facebook decides to update the settings it changes your current settings or resets them to where you have to go back and reset them yourself? why cant they stay the same with the new update? I'm sure these questions cant be answered unless you get a hold of the Zuck man himself but it is just interesting to ponder.  and maybe it is good that they reset because it reminds you to go and reassess and readjust your settings but how come you never or rarely if ever get an email about your privacy settings changing? and also why is the privacy setting menu not more prominent on the page? just some design to think about..I also don't like how when Facebook changes, like with this new timeline thing, how you are just forced to change with it, what if you don't want it, what if you want to keep your old setting? is there a way to do that? should there be? could there be? and also how will this timeline feature affect privacy? will it make it easier for people to find old posts that you may not necessarily want shown? and similarly with this opt-in stuff why isn't the default to select opt-in instead of automatically being opted in and you have to select opt-out?
