We give an "outside" review of loop quantum gravity, starting from Ashtekar variables and finishing by a brief description of some new results, like graviton propagator and black hole entropy calculations; we also discuss some current problems. Relevant review articles are: H. Nicolai, K. Peeters and M. Zamaklar, Loop quantum gravity: an outside view, Class. Quantum Grav. 22 (2005) R193-R247 [hep-th/0501114]; A. Ashtekar, Loop quantum gravity: Four recent advances and a dozen frequently asked questions, arXiv:0705.2222 [gr-qc]
