Does anyone here use Google bookmarks? http://www.google.com/bookmarks/ Do these offer any benefit to SERP whatsoever?
I don't think so ... as google bookmark is private bookmarking it shouldn't have any effect on SERP. But if you are signed in with google toolbar, it should in SERP that link is from your bookmark.
Hasan, although it is private bookmarking, Google will not need to send a public crawler through one of its one sites to find out which sites people find informative. I will not be surprised if these bookmarks hold value and contribute towards Googles efforts of finding valuable and informative websites and bump them up in SERPs.
