February 13th, 2008, 11:27 PM #1Paper: Can Social Bookmarking Improve Web Search?
A recent 11 page paper analyzed 40 million bookmarks from del.icio.us to see how social bookmarking sites impact search engine sites.
The findings were "currently [social bookmarking sites] lack the size and distribution of tags necessary to make a significant impact."

One interesting paragraph describes how the meta information (on a webmaster's site) has fallen out of favor and Google Co-op (where webmasters can label their sites with "topics") has replaced "traditional" <meta> information in the head.
However, unlike social bookmarking, these metadata
approaches require site owners to know all of the labels a
user might attach to their site. This leads to the well studied
“vocabulary problem” (see , ), whereby users have
many different types of terminology for the same resources.
Ultimately, unlike previous metadata, social bookmarking
systems have the potential to overcome the vocabulary problem
by presenting many terms for the same content created
by many disparate users.

OK - OK I downloaded it!
Wow -- it is dense and I'd be reticent to critique the research of Stanford dudes!
I agree - it is interesting and certainly very relevant to those interested in search/SEO.
Along with your excerpt, I found this interesting:
"These results suggest that URLs produced by social bookmarking are unlikely to be numerous enough to impact the crawl ordering of a major search engine, and the tags produced are unlikely to be much more useful than a full text search emphasizing page titles."

I would tend to disagree with this part of the statement you quoted above, OTProf: "... tags produced are unlikely to be much more useful than a full text search emphasizing page titles."
I think that multiple tags from multiple users of a social bookmarking site would aid in finding results due to variety and diversity.
If a webmaster has to create a [rigid] standard of [pre-defined, pre-set] terms, some terms may be missed.
I do agree with the main point of the article that social bookmarking sites have not eclipsed the search engines yet.
Although social bookmarking sites have not eclipsed the engines, they are beneficial for many reasons one being that social bookmarking allows more flexibility and the inherent interaction is a plus too.
I found some individual nuggets of useful information in that paper

Without trying to miss the point here, the article states that there are 115,000,000 book marks in existence. So for one thing I'd say the potential is enormous indeed and secondly if someone were to have a mere 1% of that ~ Say 1,200,000 bookmarks I would think that could be a very good thing where one's rankings are concerned.

Personally, I'm skeptic about social bookmarking's ability to improve search ranks directly. Unless your content is super sticky or really viral, its unlikely that the content will get on pages with high enough page rank to materially impact your own! Even if they do, the changes should be short lived due to the dynamic nature of digg/delicious homepages.
Indirectly it **may** be a good thing but only if (1) again your are on a high traffic page, and (2) **if** once you are on a high traffic page and people subsequently write about you on their blogs or link to you from there websites. It's possible, but improbably for a vast majority of submissions.
Just my 2 cents
