This really deserves its own thread. I've included everything I've been able to find so far (mostly from Smashboards), and will update the first post accordingly as more is found. Read it here so you don't have to scour that shithole that is smashboards.

You basically just repeat the first part of your dash animation over and over again. You can cancel said animation and immediately go in the other direction, and you can also cancel said animation and attack with smashes / tilts.
Just hit the analog stick repeatedly in the direction you want to go, as if you were starting a dash over and over and over. To dashdance in place (and turn on a dime while doing this), you need to move it back and forth rapidly.

Reversing your facing in a jump
Simple and useful. Run in one direction, and then jump and change directions at the same time. You'll jump and turn around, but continue moving in the original direction. A great way to use your back aerials.
edit: here's a video of Mario doing his B-air with it

Pit's Wing Cancel
http://smashboards.com/showthread.php?t=141451
This is basically similar to a double-jump cancel or a (faster?) shuffle.
edit: sorry, not 'really' like a DJC because, well, you don't have the freedom of movement that you do with the others. It's arguable whether or not this will be useful at all.

Some C-stickery
Lee Harris from somewhere said:You can now smash the C stick up while running and your character will do their smash while sliding far. I know you could smash up while running in Melee but it is done much easier this time and it is more effective because you slide into place. It is cool as hell. Check out the videos on the Wifiwars post to see it done.

Lucas PK Waveland
the guy who made the video below said:Lucas has a PK fire waveland that is done by short hopping a PK fire, which sends you backwards while keeping the enemy at bay with a solid projectile. Running, reversing your jump and THEN using PK fire is a great way to cover lots of ground, fast while leaving a projectile in your wake.

Glide cancelling
dmbrandon on smashboards said:People have seen Pit's wing canceling. Too bad that's not useful when you play against characters who are controlled by people. >_> Basically, when you glade, aim towards the ground and attack. The attack that comes out, when landed, will lose all lag frames, and will be able to combo, throw, or whatever you want. :D
------------------------------------------------------------------------------------
Shield Cancel Grabs
dmbrandon on smashboards said:Like jump canceling, if you tap the shield, and grab, the throw makes your character move faster, and the range is increased. EXTREMELY USEFUL.
Side note: the jump-cancel grabs of Melee are not in Brawl.
------------------------------------------------------------------------------------
Jab Fakes
dmbrandon on smashboards said:Most characters can do this. We know the spacies can't. How it works:
Jab once of twice, and during the last few frames of the second jab, you can shield quickly (Press the button, the shield shouldn't appear) and break it into either another jab, tilt, smash jump, grab or roll. People like Ike, and DeDeDe use this to it's maximum potential.
"Spacies" are the space animals, if you couldn't figure it out.

From err on smashboards:
