I agree that RSS is a poor way to consume to consume social news sites like Hacker News. It's a fantastic way to consume blogs, especially infrequently-updated ones. Why would I flip though 100 tabs in my browser every day to see which ten blogs have new posts when I can open my RSS reader instead and see all the new content at once?
Exactly, that's the time consuming part. Not a lot of people are following a 100 blog, I was. I remember checking my rss reader every 2 minutes to check a new article.
The only solution I found to get back to normal life was ditching my rss reader. Now I just the read 3-4 blogs frequently and check the others from time to time. I enjoy the design of each blogs. It's part of the atmosphere and of the read.
