If you have the habit of reading blogs, then reading them via RSS should be a piece of cake for you. I mainly use Great News; Great News has some blogs pre-installed, but I still find it insufficient. At first, I would subscribe to the RSS feeds of those well-known blogs, but feeling that they were not enough, I randomly subscribed to blogs linked by these well-known ones. Later, I found out that the quality of those blogs was not as good as I had imagined. Afterward, I would subscribe to any blog with a PR greater than 6. Yesterday, I found the 100 most popular Feeds globally, and some of them were ones I had already subscribed to before. The quality of these feeds is all very high, in English. If your English is strong enough, I recommend subscribing.
