Overview

Why Would I Want to Use Flickr or Del.icio.us?

When you want to find Creative Commons Licensed photos for use in a course. Flickr's advanced search capability allows you to designate licensing options as well as keywords: http://www.flickr.com/search/advanced/
When you want to create community around a topic where photos make sense to share. For example, an architecture class might create a Flickr group (or join a larger one) where photos of particular architectural types might reside.
To create a photo repository on any topic/subject.
When you want to offer short (90 second) videos on anything from How-to's to introductions to more ephemeral concepts. http://www.flickr.com/photos/tarabrown/2487834877/
When students create short videos for class, this is a good way to keep them out of Angel (and thus out of the 1GB course limit). YouTube (which Cole will be discussing) is also good for this. http://www.flickr.com/photos/ciro/2610019719/

When links change and you don't want to alter your course materials all the time to keep updated. For example, you can create a tag for a course, and simply link to your del.icio.us account via that tag. Then the bookmarks are gathered automatically. IST's SRA111 Bookmarks
When you want students to send links to you as well. Have them send them via del.icio.us
When you want to create an evolving resource together, tagging is a really good way to do it
Any list created in del.icio.us can be aggregated using RSS.

Portability--when students need to move from computer to computer, their bookmarks go with them.
Collaborative Resource Development--Both Flickr and Del.icio.us allow you to collect resources of a specific type (links or images/video)
- students can "send" resources to the group in the system, or just to the instructor, and if tagged appropriately, everyone gets a current resource that's constantly updated
- distributed resources. If students/faculty agree on lexicon, then students can aggregate their own resources in Flickr or Del.icio.us and use the tags to find all the resources tagged by everyone.
- used to build collective intelligence
- connect with individuals and experts outside of the classroom

I typically use a Social Bookmarking assignment with my IST students. Once the students see delicious they are hooked. Social Bookmarking Assignment
del.icio.us: great for giving your attendees of a class/workshop/presentation a nice little package of everything you mentioned. Gives participants a chance to relax and not worry about writing down URLs, instructor gains their attention.

del.icio.us plugin for Firefox makes it very easy to tag a site in del.icio.us and manage your other bookmarked sites.
