When DC Comics announced their New 52 initiative, there were a lot of reading guides online for the various New 52 series, which were coming and going, the best and the worst and so on.
Now that the DC New 52 is in full swing, however, you might be looking for something more detailed, a reading order guide to how to read the DC New 52 or who DC Comics's new or relaunched characters are.
Presented here are some guides to the DC Comics New 52 universe I've used or that have impressed me (plus our homegrown edition). If you've got more, please leave them in the comments section and I will continue to update this post. What we're looking for are guides on how to read and understand the DC New 52, not just recaps or reviews of the first issues.

* Comicosity - Read Between The Lines: History of the DC Universe 3.0
A lot of hard work went into Keith Callbeck and company's timeline of the DC Comics New 52, which puts the major events of the New 52 in chronological order. They sorted through over 700 comics; this list is especially good for understanding how some of the New 52's more far-flung titles like Demon Knights, Shade, and All-Star Western fit into the grand scheme.
* The Unofficial Guide to the New DC Universe
This wiki is an offshoot of the equally amazing Unofficial Guide to the DC Universe, which catalogs and includes details almost every post-Crisis on Infinite Earths DC comic, along with character chronology information. The new site, editable for registered users, is building the same kind of database for the New 52, also with chronology information. For detailed, issue-by-issue questions of who's who and what happened when, this is your source.
* DC Comics Database
Also good, with maybe a smidgen more artwork but slightly less chronological information, the DC Comics Database also includes issue lists, notes, and synopsis, as well as creator credits. They've also got a great mobile site for your superhero questions on the go.
* Tor: Reader's Guide to the New DC Universe
Though Tim Callahan's reader's guide started out as snapshots of the initial DC New 52 series, he's added to it with addendum updates for the Second and Third Wave series. This set of posts may not be as technically detailed as some of the others, but it stands as a good guide to how the New 52 has unfolded over time with short write-ups of all the books.
* DC New 52 Trade Paperback Timeline
Last but not least, if I can be permitted a plug, some readers still haven't noticed that the DC Comics Trade Paperback Timeline now includes DC New 52 books! The timeline contains all the New 52 Vol. 1s, and pretty soon it'll be time to add the volume twos. As always, the DC TPB Timeline offers a clear reading order for how to read the New 52 collections, as well as explanations for why the books are listed the way they are. Our New 52 TPB timeline follows the "old" DC Universe timeline, and makes reference to events of the past where they're still in continuity.
And even though you can go to the DC Universe Trade Paperback Timeline for all your reading order information, here's a snapshot of the guide to all the DC New 52 volume ones -- you can find more information and future volumes on the timeline.
* Justice League: Origin (review)
* Superman: Action Comics: Superman and the Men of Steel
Both of these titles take place around five years prior to the present. The story in Action Comics takes place before Justice League, but DC published Justice League first and meant it to be the starting place for the DC New 52.
* Green Arrow: The Midas Touch (review)
* Flash: Move Forward
* Captain Atom: Evolution

The Static Shock book mentions Hawkman, Captain Atom, and the Teen Titans; Flash appears in the Captain Atom book.
* Supergirl: Last Daughter of Krypton
* Superboy: Incubation
* Teen Titans: It's Our Right to Fight

* Batman: Detective Comics: Faces of Death (review)
* Suicide Squad: Kicked in the Teeth

* Green Lantern: New Guardians: The Ring Bearer
* Green Lantern: Sinestro (review)
* Red Lanterns: Blood and Rage (review)
* Green Lantern Corps: Fearsome
The Green Lantern book is most closely connected with the "old" DC Universe, taking place right after War of the Green Lanterns: Aftermath. Green Lantern: Sinestro, Green Lantern: New Guardians, and the Red Lanterns book all interconnect.
* All-Star Western: Guns and Gotham
* Aquaman: The Trench
* Fury of Firestorm: The Nuclear Men: God Particle
* Wonder Woman: Blood (review)
The All-Star Western, Aquaman, Firestorm, and Wonder Woman books are mostly independent from the rest of the DC Universe in their first volumes.
* Batman: The Dark Knight: Knight Terrors
Batman: The Dark Knight: Knight Terrors contains a "Night of the Owls" issue, placing it more properly with the New 52 Vol. 2 volumes.
