To be fair to DC, most of their titles are fairly stand alone. Final Crisis has intentionally been kept out of the regular titles. If you read Superman/Action Comics you'd never know Final Crisis is happening. Green Lantern/GL Corp is working on its own story in the aftermath of the Sinestro corp war (which is really good....I'm looking forward to The Blackest Night).
JLA/JSA are doing their own thing and have no crossovers.
Booster Gold is great fun and each issue is more or less a stand alone story as part of a larger tapestry.
