It's new. It's shiny. It's finally here.
I encourage everyone to dig through all the menus and buttons available to you in this new version. A major shift in the new site is more focus on community-oriented features and better ways to find content that matters to you, and you now have a lot more capability than you had before to help you in these areas.
Over the next few days we'll be posting some "tips" to help you get reacquainted with the new site, so keep an eye out for that. In the meantime, definitely spend some time exploring. You just might be surprised.
