I often see multiple subscription options in the head of a web page. For example:<link rel=alternate type=application/atom+xml title=Foo&#39;s blog - Atom      href=http://foo.bar.blogspot.com/feeds/posts/default /><link rel=alternate type=application/rss+xml title=Foo&#39;s blog - RSS      href=http://foo.bar.blogspot.com/feeds/posts/default?alt=rss /><link rel=service.post type=application/atom+xml title=Foo&#39;s blog - Atom      href=http://www.blogger.com/feeds/123456123456123456/posts/default />Or:<link rel=alternate type=application/rss+xml title=RSS 2.0      href=http://www.google.com/blog/feed/ /><link rel=alternate type=text/xml title=RSS .92      href=http://www.google.com/blog/feed/rss/ /><link rel=alternate type=application/atom+xml title=Atom 0.3      href=http://www.google.com/blog/feed/atom/ />When subscribing, is there any reason to prefer one URL over the others? (I emphasize the subscribing part because it seems like most comparisons between Atom and RSS are targeted toward publishers or tool implementors)
Is there any difference between subscribing via Atom or RSS(2)?
