What are good expositions of spectral sequences, which include a thorough introduction to the topic as well as the most important examples of applications - maybe with an emphasis an topological and/or operator algebraic uses.
I know that the wikipedia article is quite extensive, but I'd like to have something... nicer.
I really like the way Bott & Tu develop spectral sequences in "Differential Forms in Algebraic Topology". It would be an especially good choice if you happen to have some familiarity with de Rham cohomology; they begin by just sort of easing you into the whole idea by proving the isomorphism of de Rham cohomology and Cech cohomology by constructing a double complex whose cohomology is isomorphic to both of those.
Of course, they only give uses for spectral sequences in topology. I think they mainly introduce them to be able to give the spectral sequences for the homology and cohomology of the total space of a fibration. In this application there is particularly nice geometric intuition for the algebraic machinery, which I found very useful for trying to get to the bottom of what these things really do.
