The Spoiler has an interesting origin — she took up crimefighting in order to "spoil" her loser-dad the Cluemaster's attempts at crime-doing. In the process, she got a taste for heroism and found she wasn't too bad at either. Oh, and she thought Robin was reaaaaally cute and this was the best way to hang with him!
After her debut in Detective #647, she became a mainstay of the Robin series where she has gone from annoying hanger-on to ally to girlfriend over the course of several years' worth of issues.
Stephanie was at the heart of one of the best storylines of the series, too, when she became pregnant and had to decide what to do next. It was during this storyline that her relationship with Robin (not the father but certainly a more reliable and responsible friend to Steph than her baby's father ever was) matured.
She also reevaluated her own reasons for crimefighting and staying in the game (an ongoing process— hey she's young) starting shortly before this (right in the middle of Cataclysm where Huntress gave her a good scare and a lesson in how NOT to crimefight), and at the end of 2002 she hit a very bad patch, being rejected by the Birds of Prey and Batman as a protege and learning that her estranged, criminal father had died.
Things looked back up for her when Batman chose her as his new Robin when Tim briefly retired, but the ensuing events that led to "War Games" had irrevocable consequences for Stephanie.
