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.
