Is Del.icio.us Delicious?

I tend to be a serendipitous searcher of the web with few "Favorites" that I go to on a regular basis. I can see the advantage of Del.icio.us in terms of compiling a research portfolio on a particular topic or area or if a person does have favorites and uses multiple computers. I will have to try this one out a bit more before incorporating it into my web use.
