When RSS feeds go bad

Perhaps I am the only one but when good RSS feeds go to summaries instead of full feeds there quickly earn one fewer subscriber. The value proposition must be there as good bloggers like Guy Kawasaki are now sending out only summary feeds. Not long ago I responded to one of Kawasaki's posts and helped to expand a project he was working on. Now, however, the feed will simply fall out of my reader and someday be replaced by another.
