With all the social media emphasis that we've all been doing and will continue to do, I wanted to share a quick shortcut to make sure you've got your permissions and privacy under control.
Visit mypermissions.org. You can click each of the icons to take you to the permission controls of that network.
Basically if you've connected your Facebook account to a lot of services over the last few years and you don't necessarily still want to keep your account connected to those older sites any more, you can revoke access to that site. The same goes for Twitter, Google, Yahoo, LinkedIn, Dropbox, Instagram, Flickr, Foursquare, AOL, and Microsoft Live.
It's a good idea to check over your permissions every couple of months, especially if you're concerned about any sites that are accessing too much information or even sharing it.
