What is the difference between a zeta function and an L-function?
Oh, thanks for the edit. From what I understand, L-functions are from representations (of the Galois group or so) and zeta functions are ... err, I don't know where they come from, but when they appear they have their own flavor. |

Some bounded theorem of algebraic stack of coherent sheaves
See FGA Explained, or Mumford's book on curves on algebraic surfaces. I think you can obtain a p only depend on the hilbert polynomial. |

Do complete non-projective varieties arise “in nature”?
@Piotr he is talking about small resolutions, not blow-ups, which may go out of the algebraic category, if I understand it right. |

Why are derived categories natural places to do deformation theory?
And the cotangent complex is not constructed as an object in the derived category of quasi-coherent sheaves, it is an object in the derived category of O_X modules whose cohomologies are quasi-coherent. Sorry for being picky. |

A typo in the triangle of cotangent complex... |

Degeneration of varieties to simple normal crossings
A good reference on this direction can be find in section 5 of math.berkeley.edu/~molsson/HofM.pdf |

Is there a “geometric” intuition underlying the notion of normal varieties?
See a explanation here: mathoverflow.net/questions/45347/… |
