The first is the creation of a "Recent Activity" box on your YouTube channel. This box will provide your viewers with a snapshot of recent changes you've made to your public channel, making your channel more dynamic, fresh and timely. For example, if you recently added a new favorite to your channel, visitors can find this favorite in the new Recent Activity box (as well as in the usual "Favorites" box). The Recent Activity box will also consolidate the separate "My Recent Ratings" and "My Recent Comments" boxes into this single activity window.
As always, we give you maximum control over how your channel is configured on the channel design page. And now, the Recent Activity privacy settings page (also available in the upper-right corner of the Recent Activity box) lets you choose what activity you want to appear in the Recent Activity box. It's important to note that we've set your initial Recent Activity settings according to what you already publicly show on your channel today - so, for example, if you're not already showing the Favorites box on your channel, then the Recent Activity box won't suddenly start showing new favorites you make.
Regarding bulletins, we've listened to you, and most of you didn't see the value in bulletins as they are today. So, we're taking a first step to make bulletins more useful. Although the bulletin box will be going away, now you can broadcast a bulletin directly to your channel visitors in your Recent Activity box. This not only provides a fun place to shout out personal updates and news, but also provides an additional way to communicate and engage with your channel's fans.
We hope you like these changes, and are always eager to hear your feedback - so please feel free to share your thoughts with us!
Update: As some people have noted, the "new" bulletin system no longer sent your bulletins out to your friends. We've just finished rolling out the next update to our bulletin system - your bulletins will now show up on your friends' homepages in their "Friend Activity" box.
