Like collaborative stuff described in the THing 9, de.licio.us and similar tagging services provide a way for one person's tags to be accessed and built upon by others with similar interests, who wouldn’t even be connected otherwise. So it’s social networking/ research. So fun. And like Ms. Gilroy said in the podcast, traditional educational resources like syllabi and reading lists can be built online with de.licio.us, accessible to anyone with an account. It’s a useful tool, cuts down on wasted time, and makes more time for more innovation and ideas. It’s the exponential learning explosion of the knowledge society.
De.licio.us’ ”Filtering by authority” helps cut through the superfluous extra information, that accumulates with ease of use of web 2.0 “things”, so the problems are handily self-managed.
