Wasted time compared to what? Not getting the news/posts/whatever? Having someone/something else that do the selection of what "should" be relevant to you and send you from the links to the full text? HN does a good enough filtering, if you have it on your feed list. Some other aggregators can do the same. And the individual blog owners don't make a lot of posts daily. And more important than that, depending on your feed reader, you may get at most a headline, and then decide to read a bit more, or the full article. And of course, decide what feeds to follow based on their quality or your load/required time to go through it. All of that is miles away from going to each site, see the already read content, ads, images/js. And we already know the dangers of letting something to do the selection of what we should read instead of us.
