GRBs had been a totally not understood phenomenon for about 20 years
because of the absence of any scale indicating their distance. This
changed implicitly in the early 90's with their apparently isotropic
distribution on the sky and explicitly in 1997 with the observation of
the first red shift that put them at cosmological distances. Since
then, 3 more spacecraft have observed GRB and determined their
redshifts, spectra and time evolution. After all this progress many
issues have been resolved while other new ones have emerged. With hind
sight we can now check our earlier proposals and see how they fare in
view of the latest developments.
