Google+

Facebook has announced some long over-due changes this week - primarily the ability for users to approve tags, including photo tags, before those tags show up live on their profile. Now, when a friend tags you, a dialogue box asks you to choose from a set of options, including removing the tag. These changes come hot on the heels of Google + becoming more widely available, and they are all things that G+ already does. Interestingly, and in a classic Facebook move, though these alterations will be launched later this week, they will not be default. The default setting will still be that any photos in which friends have you tagged, will automatically go live on your profile. Users will have to go into their privacy setting and toggle the approval feature to an "on" position.

A recent Retrevo Gadgetology study discovered a large percentage (76%) of Facebook users saying they've changed their privacy settings. That's probably a good thing for Facebook users but it doesn't say a lot about how much Facebook default settings are in sync with the average user. It's a good thing for Facebook users because this study also found that Facebook has become a very popular way for people to check each other out both socially and for business.Read more
