Other approaches that come to mind are:

Asymptotic Safety http://arxiv.org/abs/0709.3851

Causal Dynamical Triangulations http://arxiv.org/abs/1105.5582

Steinacker's interpretation of the IKKT model, originally proposed for strings http://arxiv.org/abs/1202.6306

Group field theory http://arxiv.org/abs/1112.3270

Tensor field theory http://arxiv.org/abs/1112.5104

Both GFT and TFT have some relation to LQG.

Gu and Wen's condensed matter approach http://arxiv.org/abs/0907.1203

Markopoulou's quantum graphity http://arxiv.org/abs/1201.3398

Vidal's note about LQG and tensor network algorithms in condensed matter http://arxiv.org/abs/0907.2994

Swingle's note about AdS/CFT and tensor network algorithms in condensed matter http://arxiv.org/abs/0905.1317

Horava-Lifgarbagez gravity http://arxiv.org/abs/0901.3775

Also there are efforts in string theory to get a non-perturbative model that works in positive curvature spacetimes like the Twistor Matrix Model http://arxiv.org/abs/1112.5210

BTW, string theory does have models for positive curvature spacetimes http://arxiv.org/abs/hep-th/0301240
There are so many quantum gravity models, each identifying with the author name. Do you know know the best way or journal to create a new QG theory under my name. So instead of saying "Gu and Wen's condensed matter approach" or Horava-Lifgarbagez gravity. It's my own name with so and so approach so others would quote it's mine when mentioning it? Maybe I can sneak it into arxiv even with no plan to publish it in a real journal? Maybe that is enough to claim ownership of the model?

Maybe there are like 50 plus QG models with only 15 discovered. So it's cool to add some your own like "create you own QG" in light of the very possibility that string theory and LQG will come into dead end someday. Then they have to go back to beginning.
