5. Who ’s Who in Social Bookmarking Digg.com Considered the #1 SB website 1 1 "Top 20 Social Bookmarking Sites| June 2009." The eBusiness Knowledgebase . June 2009. EBizMBA. 15 June 2009 < http://www.ebizMBA.com/articles/social-bookmarking >. 2 Arrington, Michael. "Feature Overview of Delicious 2.0." TechCrunch .

7. Advantages Public Both Private (w/n OCGR) 1. Ppl can find & bookmark web pages that haven ’t been noticed by automated computer programs 1. More intuitive ( “human touch”) 1. Information gathered from rankings useful web metric 2. allows for exploration and more browsing 2. automatically generates “related” tags 2. Consolidates bookmarks from various computers and share bookmarks with contacts 3. Makes users more comfortable with content 3. allows users to quickly share news about events in real time 3. search engines will discover the link to the page each time it is posted at one of the social bookmarking sites
8. Disadvantages Public Both Private (w/n OCGR) (1) spammers have started bookmarking the same web page multiple times a lot of (unrelated) popular tags (1) mistagging errors can be extensive (1) no mechanism to indicate hierarchical relationships between tags (2) SB can be distracting and confusing (2) no mechanism to indicate hierarchical relationships between tags (2) Catch-22: You cannot get the links if people can't find you, and people can't find you without the links.
Public (3) Social bookmarking websites are more user-friendly and popular than NIAID, thus making it a comfortable venue for exploration Both (1) Tagging is done by human beings, who understand the content; as opposed to software which algorithmically attempts to determine meaning Private (1) Can rank a resource based on how many times it has been bookmarked by users, which may be a more useful metric b/c (a) it shows popularity (b) bookmarking is a purposeful action, so accidental clicking is reduced
Both (1) no standard set of keywords (i.e. no controlled vocabulary), no standard for the structure of tags (e.g., singular vs. plural, capitalization, etc.), spelling errors, tags that could have more than one meaning, synonym/antonym confusion, unorthodox and personalized tag schemata from some users ,Acronyms present ambiguity ,here is no synonym control in the system; tags have seemingly have similar intended meanings ( Eg. “mac,” “macintosh,” and “apple” all being used to describe materials related to Apple Macintosh computers) (2) eg. a site might be labeled as both cheese and cheddar, with no mechanism that might indicate that cheddar is a sub-class of cheese Private (1) Traditionally, OCGR has used a hierarchy; also, it will be harder to “reorganize” data
