I am subscribed and get my Angular Newsletter weekly from this site[1].

Although the newsletter also involves the anticipated changes for the 2.0 version, they do provide good articles as well related to the latest Angular release.

If you are on Twitter, you could also follow @AngularJS[2].

Also, Egghead[3] and Airpair[4] normally provides good articles related to AngularJS, although the latter has more diverse web topics.
