Social BookmarkingStarted in mid 1990s e.g. Backflip , barely surviving http://twitter.com/backflip_status
Commercial ventures failed when dotcom bubble burst
Reinvented as ‘Social’ Bookmarking in Web 2.0 era when Del.icio.us introduced tagging
Many players in ‘free’ Web 2.0 arena Furl, Digg, Stumbleupon
Also offered as ‘enterprise’ service to businesses e.g. http://connectbeam.com/

Delicious compared with Search
What’s new? http://delicious.com/
How does delicious compare with Google search?
Let’s try a search for micro-blogging definition
http://delicious.com/search?p=micro-blogging+definition&chk=&fr=del_icio_us&lc=0&atags=&rtags=&context=userposts|francesbell|&context=all||
http://www.google.co.uk/search?source=ig&hl=en&rlz=1G1GGLQ_ENZZ339&=&q=micro-blogging+definition&btnG=Google+Search&meta=lr%3D
How are they different? And Why?
Can search within your own bookmarks, or your network’s

Folksonomy“Folksonomy is the result of personal free tagging of
information and objects (anything with a URL) for one's own retrieval. The tagging is done in a social environment (usually shared and open to others). Folksonomy is created from the act of tagging by the person consuming the information. The value in this external tagging is derived from people using their own vocabulary and adding explicit meaning, which may come from inferred understanding of the information/object. People are not so much categorizing, as providing a means to connect items (placing hooks) to provide their
meaning in their own understanding.” Thomas Van der Wal http://vanderwal.net/folksonomy.html
