What are some examples of social bookmarking sites?

According to Will Richardson (2009), writer of Blogs, Wikis, Podcasts, and Other Powerful Web Tools for Classrooms, “Millions of people have begun using public, online bookmarking services where they can save links, annotate them with unique keywords or ‘tags’ to organize them, and then share them with the world” (p. 88). Due to this influx of social bookmarking, new sites have been appearing all over the web. According to the website eBizMBA Inc. (2009), there are 20 top social bookmarking sites.
eBizMBA Inc.’s (2009) top 20 social bookmarking sites are:
digg.com, Yahoo! Buzz, Technorati.com, StumbleUpon.com, del.icio.us, kaboodle.com, reddit.com, mixx.com, Propeller.com, Fark.com, newsvine.com, Slashdot.org, clipmarks.com, Furl.net, faves.com, dzone.com, blinklist.com, ma.gnolia.com, simpy.com, and BlogMarks.net.
While these are only the top 20 social bookmarking sites, there are probably many more, lesser-known sites. Perhaps these 20 examples are only the beginning of a social bookmarking revolution.

Midterm

Here is my group for the Midterm project :
Group 1. Social Tagging e.g.,Delicious, Flickr, etc.
Melissa - What is it?
Beth - How Does it work?
Laura - Examples?
Christopher - How Can it be used in the Art Classroom?

Since my part of the research is to find examples of social tagging sites, my question to you is...
"What are some examples of social tagging sites?"

Thanks for your help!

How can Wordle be used as a tool in the classroom?

“How can Wordle be used in the classroom?”. To answer this question, I typed “wordle lesson plans” into google. I found a Wordle blog written by Jonathan Feinberg, the person who made wordle. On this blog, teachers have started a discussion about how they personally want to include Wordle in their curriculum. Some are English teachers, some are foreign language teachers, and they are all bouncing different ideas around.
