Yahoo! Updates is a stream of people's activity, based largely on public content they've created on Yahoo!. For some time now, Yahoo! is been adding Updates into more of its products like Yahoo! Mail, Messenger and Profiles. With each new roll-out, Updates has been improving. For e.g., in Yahoo! Messenger, people can see Updates from all their Messenger friends. However, in Yahoo! Mail, people have only seen content from their Connections across Yahoo!. In coming weeks, "Yahoo'll be expanding Yahoo! Updates in Yahoo! Mail to enable you to see public updates from some of your Messenger friends and Yahoo! Contacts in addition to your Connections. Will also allow you to start sharing your Updates with friends on Facebook, Twitter, and other social networks if you want – another great improvement and big step forward. But before this, you must explore Updates settings and make sure ou know who can see what you're publishing. Because majority of events listed within Updates are inherently public activities, defaults are set to allow anyone to see them (that's, for people over 18; we've different defaults that're age-appropriate for people under 18 – learn more in FAQ). We've made sure this control is easy to find by putting it at the top of the page and that there's a single on/off check-box, with more granular controls for people who want their settings somewhere in between," writes Yahoo!.
