There are a growing veriety of socially compiled and organized content storage and distribution tools available on the Net. Perhaps the two most recognized are YouTube and Flickr. Flickr is a public digital photo album service, and YouTube is a social video distribution service. You've most certainly heard of both. As with most social resource searching, using tags for the basis of the query is the most powerful way, as when an item of information is tagged, it has been explicitly labeled with that term.

If we search YouTube for videos with D-Day, then the return will be any video with D-Day in the title or description -- and many of them will be solid hits. However, if you search for videos tagged or labeled with D-Day, then the videos were explicitly labeled with the term -- all should be able D-Day. The easiest way to do this is the search for your term, D-Day, and then in at the end of the URL that return, the argument ...search=search should appear. Change the second search to tag, and press [return]. This will return only videos tagged with D-Day.

If you want to subscribe to all new videos uploaded that are tagged with D-Day, then use your aggregator to subscribe to the following URL:

         feed://www.youtube.com/rss/tag/d-day.rss

For other tags, just substitute d-day with the new tag. Flickr works in a similar way. If you are looking for photos that are tagged with d-day, then go to the following URL:

         http://flickr.com/photos/tags/d-day

Substitute the d-day with jonquils if you are looking for photos of that very delicate flower. At the bottom left of the page you will also see the ubiquitous RSS logo []. With this link, you can subscribe to all newly uploaded photos tagged with D-Day or jonquils.

Podcasts are another source of content that is made for subscription. iTunes is the most popular source of podcasts, but another one to consider is the Education Podcast Network, an index of education related and relevant podcast programs.
