Title of the communication: 
Comparison of the  accelerating inner jet
 model to blazar observations.
Preliminary abstract:
 The accelerated inner jet model is briefly
described and a comparison to the obervations
is attempted. The optically thin synchrotron
steady-state model spectra are used in an 
effort to explain the dichotomy between
the radio and X-ray selected BL Lacs. The
emerging picture suggests that the observed
properties of a blazar are defined by both the
jet orientation and the intrisic properties
of the object.
