"Every blog I've tried to follow for years has had an RSS feed. " I follow many blogs (Rule of thumb: the fewer posts per time, the higher the content of the blog likely is) and you would be surprised how many feeds fail over time. Sometimes new domain, sometimes new URL (e.g. blog.domain.com to domain.com/blog very common). And often an RSS feed contains errors that never go away.
