Are the books you read similar in subject to the blog posts you read? I bet they are not.
To me it sounds like you are bored or tired of reading about the same material. It's burnout really. It might be the simple that there isn't much new or interesting material in your area of interest and most blog posts are rehashing the same info you already know.
Taking a break is fine. Maybe its time to explore hobbies you've been interested in perusing but have not yet had the time.
It's similar. I.e. psychology of users, building startups as I'm right now building one, so I want to learn as much as possible. Blogs are not bad, I personally just loose ambition to read it and absorb it like I do when I read the book. I know it's totally different medium, and blogs are fast, books are slow, but I just waisting time scrolling through post, while I can read a book meanwhile.
Perhaps the issue is the style of writing? SEO speak has ruined many blogs in an attempt to bring in more ad money resulting in low quality content called blogspam.
