   The \LaTeX\ manual is simply insufficient.  It doesn't even cover putting 
   thin spaces in such simple formulas as
   \[ {\cal F} = \{\, f_\theta : \theta \in \Theta \,\} \]
   and
   \[ \int f \, d\mu \]
   or the double quad space in
   \[ \theta_i \le \theta_{i+1}, \qquad i = 1, \ldots, n-1. \]

Oops.  I guess "simply insufficient" is overstrong.  One of the three
examples here is covered on p. 52 of the LaTeX manual.

It is true though, that anyone who has any serious math to typeset had
better read the TeXbook (or the AMS TeX manual I suppose).  How about the
other two examples?  And there are dozens of others.  The point is
that it's not enough to know that you can put some space wherever you want,
you need to know where you should put space and exactly how much.
