Overnight Facebook has pushed a bunch of changes that affect the way users can share information. These changes are always pitched as “functionality improvements” but never disappoint to bring with them serious privacy implications. This particular set of changes are mostly around tagging and sharing, and some changes made to privacy controls.

Check it out here.

The main points:

• You will have the OPTION to approve content which OTHERS tag you in before it shows up on your wall. Marketers and spammers will hate this, but I think it’s a good thing.
• You will have the OPTION to review and approve or reject any tag someone tries to add you YOUR content. Also a good thing.
• A feature has been added to let you look at your profile “as someone else”, giving you the ability to test your privacy settings. Another good thing.
• You will be given the ability to easily remove tags of yourself from OTHER peoples content. I know the ladies in particular will be happy about this one.
• ANYONE can tags ANYONE in ANYTHING. This one is a little nasty… Granted, if non-friends tag you it will not appear on your profile until you review and approve the post.

As with all Facebook changes one should assume that the new default settings will be the ones which are most permissive with your information (e.g. you have the OPTION to approve content which OTHERS tags you in… but you have to opt-in and turn it one first) so I’d check out the Facebook blog post, get the down-low, and go on a bit of a settings tweak.
