Could not agree more, this is the exact use case for the 'power users' of RSS. And he is right that without RSS I don't know how these low-posting-frequency sites would keep their readership. If I had to give up one, I'd give up twitter or hackernews long before that low-frequency RSS feed. Those posts are gold and for niche subjects (I'm into bio) there is no where else they are aggregated.
Tech, video games, etc.. journalists have a very different use case for RSS, which is exactly using it to monitor dozens of other information sources (including their competitors). I think they match the definition of power users, perhaps more than you and I, because that's the primary tool for their job : they will routinely have hundreds of RSS feeds and will skim quickly through thousands of items a day to look for the information that they haven't treated yet.
RSS is perfect for that matter and it is precisely the opposite of what marco and you claim is a poor usage of RSS.
