  The present status of the blazar spectral sequence is discussed, including
new findings about blazars selected with different criteria than the original
complete radio-samples. Despite extensive searches of blazars "breaking" the
sequence, the original idea proposed 10 years ago, still seems to hold. On the
other hand the forthcoming launch of the GLAST satellite will provide a new
selection band for blazars and blazar related populations as well as fantastic
progress on the spectra and variability behaviour of presently known blazars.
The order of magnitude increase in sensitivity of GLAST will allow to detect
gamma-rays from jets with lower power and/or lower beaming factor, thus
sampling a much wider population.
