I'm starting this thread based on a comment on the current "Oxalic Acid or Evaporust" thread. I'm very careful about always applying grease to parts that thread together--including all nuts and bolts--as well as seatposts, stems, etc. Should I be using anti-seize compound instead, and if so when? Is anti-seize preferable to grease for seatposts, for example? Bottom bracket fixed cups? How about routine nut-and-bolt assemblies? If there's some rule of thumb about this I'd like to know what it is.
