Google Reader's blog announced that the feed generator for pages that don't have feeds will no longer be available starting from September 30. Google says that not many people used this feature, which is not surprising, considering that it's quite difficult to find it.
Unfortunately, Google Reader's feeds looked terrible. The title for each item was "generated feed for [URL]", the feature didn't detect new images and the feeds were updated when the new versions of the pages were added to Google's search index. Here's Google Reader's feed for google.com and here are the changes found by Page2RSS. Page2RSS found 8 changes in September, while Google only found one. Page2RSS has another important advantage: the service constantly monitors web pages and it's not tied to a search engine that indexes billions of web pages.
