>Imagine that I kept only 15 urls. Now I have to look at those each day to see what's new. There's a high probability that the news about VFP will look alike from blogs to blogs. Perhaps updated on different days. So if I want to be sure to have all the informations I'll read them all. Who knows there could be different bits and pieces of informations from one place to the other.

UT does some of that by querying the blog list we have to see what is new. It provides the updated date.
