Glottal theory and other points

Hello Piotr:
What are the fundamentals of the glottal theory? Is it typologically
acceptable? - I remember your remarks about nostratic's huge bunch of
consonants.
Is there compatibility between glottal hypothesis and laringeals theory?
How is it explained the fade of *b? Is it similar than Celtic and Armenian
case?
Personally I always find PIE a little bit strange regarding the consonants
inventory: there was a complete development of stops while a very poor
show-up of fricatives.
By the way, how can an analytic language become a synthetic one? I always
have thought of this phaenomenon as resembling an endless circle: synthetic
(flective) become analytic ("atomic" like Chinese; then, in an agglutinative
process finally returns to synthetic. Am I right?
Kindest regards and wishes of the Happiest New Year,
Manuel
