There's a number of Oracle folks that really know their stuff.
If you don't hang out on mailing lists and search them out
at IOUG though, you'll never get to pick their brain, as you
usually don't get them when you contact support.
2 exceptions: there are some good folks that monitor the
MetaLink forums, many of them veterans of several years
of Oracle's forums on CompuServe.
Tom Kyte is another exception, he is very accessible through
his website and usenet.
