I absolutely LOVE Accelerando. I've recommended it to everyone I meet for years.
If you're looking for other great sci-fi reads:
John Ringo - Live free or die
John Varley - Titan (-> Wizard / Demon)
Charles Stross - Singularity Sky
Vernor Vinge - A Fire Upon the Deep / A Deepness in the Sky
Robert Heinlein - Stranger in a Strange Land
Dan Simmons - Hyperion
Alastair Reynolds - Revelation Space / The Prefect
Orson Scott Card - Enders game
Isaac Asimov - Foundation
I think of the books by Charles Stross halting state and rule 34 are both better books and give a better 15 minutes into the future feeling.
Halting state might be a bit dated but rule 34 absolutely holds up.
I think Singularity Skies pales in comparison with the depth and breadth of Accelerando.
Ender's Game and Foundation are timeless classics, and I suspect, Accelerando will eventually become one.
