As always, fascinating results. I am part of the very smallest segment, in that I use an image-based social bookmarking service, ScrnShots, to keep track of a lot of my design inspiration. I'm not a nut about it though, and I definitely "cruise the galleries" as well.
I was surprised to see Local Bookmarks take the #1 spot. Seems like that could get unwieldy to me, and that local bookmarks sort of lack the annotation ability to deal with this specific task properly. More power to ya though, if you got a system, that is awesome.
I'll leave it up for a few more days, and hopefully get a new poll up later this week. Feel free to come up with ideas!
