Add visuals to tags, bookmarks,

I was just reading Larry Ferlazzo blog and tried out the Favthumbs as a way to share those bookmarks and items tagged with Del.icio.us with students.
The Favethumbs looks like a neat tool. Here mine:

TOOLS TO CREATE SIMPLE INTERNET SCAVENGER HUNTS:
There are several simple web applications that teachers can use to easily have a list of websites where students can go to find the answers to specific questions on a scavenger hunt. The ones I list here are particularly accessible to English Language Learners because they provide screenshots of the websites as well as their url addresses, and they also don’t require a teacher to register to use them, either. They include:

FAVTHUMBS: Favthumbs provides thumbnail images (and links) of bookmarks saved on your del.icio.us account. Favthumbs might just be one of the easiest ways for a teacher to create an accessible webpage for students doing an Internet “scavenger hunt”, or if they just want their students to focus on a few specific webpages for an assignment. All a teacher has to do is create a tag on their del.icio.us account and give students this url address — favthumbs.com/ (your del.icio.us username)/ (the tag you gave the links). Students will see thumbnail images and links to the sites you’ve bookmarked.

MINMU: With MinMu, all you do is paste the url addresses of as many webpages as you want into a box (no registration is required), and you are given one url address for all of them. Click on it, and you’re shown a screen that not only shows the links to all of the sites, but also thumbnail images of them.

Social tags & bookmarks, - like tea & cookies, they go together

Del.icio.us is a way to create and use tags.

What potential do I see for this tool? e.g., for teachers, for students, for class assignments, for curriculum development.
Well I do agree that using social bookmarks or taging is better using a web service lic Delicious than marking favorites on a specific computer. The extra advantage is that you can look up a url and see how others have tagged it- this will lead you to more sites with relevant content. However I guess I need more time to work on the social sharing part. I think its like looking at a picture not all eyes will have the same perspective nor the same words to describe a site.If there is a course project, or specific topic that you want to have information on you can use your tags in delcious search, but personally I like using my Google reader for that too,- with the Reader I get the site and the summary of the articles.

Digg is also a popular tagging.I have heard a lot about it for educators but haven't tried it yet. so at this point I'm not sure how each of the following compare: Delecious, Digg, Reader or even advanced Google searches, or data base searches - they all find websites and store the ones we want to return to.
