lol - shoulda typed "...delicious, because..."
delicious is an social bookmarking site. basically, its like having an online favourites list.. it means that you can access your bookmarks from any computer and you can network with people you know - so they can checkout the things you find interesting. ...and you can see other people who've marked the same stuff as you - and see things they are looking at, etc.
my uni course covers a lot of social/new media things so i had to write an essay about it last term! its really a pretty handy tool.
