As opposed to the previous default state of the site, you may want to set a custom feed as your GCM landing page. It's that useful. Instead of having to click through the (kinda insanely large now) site, you can tailor a feed to show basically whatever you want: select authors, topics you've followed, fellow users, unread content only... the list goes on.

First, to find your personal feed, near the top right of the screen you will see a newspaper icon in the orange bar below your user information.

That brings you to the default view, which is Unread Content.

Here you'll see a variety of options to tailor your custom stream to do almost anything you like on the site. I'll spare you going through each item in detail individually, as it's all quite self-explanatory. You can choose tagged content, type of content (news, forums, blogs, status updates, etc.), read/unread only, content you've participated in or started, followed content, and finally, how it's sorted.

Depending what kind of device you're using, you can also choose Condensed or Expanded. Condensed just gives you the title and link while Expanded offers a truncated version of the content as a preview.

Once you've decided on your changes, you can save this stream using the save prompt below. You're allowed to have multiple custom streams so name this new stream and it joins the others.

Once you're done customizing your stream, Click Stream Options at the top right of the selection drop-down, and your choices become your default custom stream. Every time you click that newspaper or visit your stream, the selections you've made will remain in place.

That's it, enjoy the new site!
