Delicious and social bookmarking

Yes, sites like Delicious definitely have the capacity to serve as a research tool for those looking for information, particularly if searchers come across bookmarks by people that are authorities in the subject they're investigating. The open-ended tagging process helps facilitate their use as a research tool. Unfortunately, like so much of the Internet, it could be another case of trying to find a needle in a hay stack as searchers may have to wade through a plethora of irrelevant or poor information to find something useful.
