A lot of people who get into online marketing, blogging and affiliate marketing spend a considerable amount of their time reading other blogs. Reading other blogs won't get you traffic and won't put you into the business.
It's more important that you spend time working and developing your own web properties the majority of the time. That would be the 80/20 rule. Anything less and you're going to take forever to get the results you need.
It's important to note, to understand what others are saying, you first have to experience the process When you do, you will quickly pick up on the small, but important information that is often hidden in blog posts to those that don't understand the process.
Try it, just get started building your blog and see how much further you get. If you already have the blog, switch up and spend more time writing than reading. When you do read, you will see that what others are saying makes more sense to you.
The more content you have, the greater the chance your blog is going to get read. Remember, you can't make money if you don't have a real audience. The faster you get them, the sooner you will be able to turn your blog portfolio into a real business.
