So if you like some page you add the URL to del.icio.us, and tag it with some relevant tags in order to be able to see it later on, and you can also send the link to any del.icio.us user, and users can surf your bookmarks as well.
"RapidShare, is a free service, where any user can upload files of up to 100 MB without registration. The user is then supplied with a unique URL, which locates the file and enables anyone with whom the uploader shares it to download the file", Wikipedia.
There are many other similar sites, and you can see a comparison of them here.
Now people can upload Movies, Softwares, etc to RapidShare et al (One-click hosting), and then add the file link to del.icio.us and tag it with a special tag.
Let's sy you want to upload a french movie called "Taxi", to RapidShare. So, you can tag the file with the follwing:
link:file-video , type:wmv , lang:fr , title:taxi
An mp3 can have the following tags:
link:file-music , type:mp3 , artist:alanis-morissette title:ironic
