I mostly follow writers, but not always.

Right now from Marvel:

Fantastic Four
Inv. Iron Man
Thor (giving it a shot with Fraction)
Captain America
Amazing Spider-Man
Chaos War (when it starts) because I love Herc and everything Pak and Van Lente did with he and Cho.
Avengers Academy
Secret Warriors
Secret Avengers
SHIELD (Limited Series of awesome)
Taskmaster (Limited series with potential)
and X-Factor

And then anything DnA (Thanos Imperitive and beyond).

Well, yeah, but you know, AFTER that!

To jackstar, I usually follow writers too. My list from Marvel is pretty similar:

Avengers (Mixed feelings)
Avengers Prime
Thor
Captain America
Amazing Spider-Man
SHIELD
Secret Avengers
Taskmaster
Wolverine (I'm starting to give it a look now that Jason Aaron's kicked off a new arc)
All those DnA titles (Looking forward to Iron Man & Thor)
