Re: Damn, I never thought of that until now.
The only reason she went herself was because the intranet didn't have an outside connection (until the story needed it to have one). She could have just as easily sent Misfit with a probe device as well as a wifi card. Either way, it's as you say: [There]is the angle that Babs sometimes wants to do her own fieldwork. Oracle would rather run her own badly executed field op (to protect Batman's identity) rather than an efficient one, which is kind of makes my point. And let's not forget, the only reason that drive existed was because Oracle doesn't know how to properly encase her hard drives in explosives to protect her data.
However you look at it, however you enjoyed it (and, hey, don't let me stop you from doing so), everything about that story makes me cringe, because there was a time (long, long ago) when Oracle knew how to marshal meta-human resources.
