Fraser Speirs (of FlickrExport fame) shares his Aperture workflow:

Someone asked me recently about how I work through my photographs after I shoot. When I go out to photograph, I shoot a lot - most people I go out with are usually surprised at the number of frames I produce. It’s not uncommon for me to take the kids to the park and come home with 150-300 images.I find that I can usually edit down 350 images to around 50 in 40-60 minutes and I thought I would share how I go about this.

He also has a more recent blog entry entitled When I Delete a Photo (almost never, basically). I have a different philosophy: I reject many photos and delete all the rejects about once a month.
