I removed two incorrect statements in the "Problems" section. 
 1) It said that d-branes have no quantum description.  Just not true.  They have a perturbative quantum description in the DBI/Super Yang Mills Theory.  They have non-perturbative quantum desciptions by various dualities, and as realizations as solitons living on other branes.  ADS/CFT gives complete, non-perturbative, quantum desc. of all of Type IIB (in ADS), including all of its brane objects. 

 2) It said the Landscape contradicts the old idea that string theory has no adjustable parameters.  Again, just not true.  The idea has always been that string theory has no adjustable parameters *as a theory*, but many adjustable parameters describing its solutions, including its vacua.  For example, the coupling constant of string theory is understood not as some external parameter (as in most quantum field theories) but as the value of the dilaton, a dynamical field in the theory.  The Landscape actually represents a dramatic reduction in these parameters: rather than an infinite continuum, these parameters can take on only finitely many values in the Landscape. But these parameters are still just describing which solution/vacuum of string theory one is living in.
