We talk a lot about developing a “strong voice” here on IFB. It's the quality of a blog that's often cited as the single most important.
Another way to think about it, are you voicing something original, or are you just echoing what you find to be the most popular? Granted nothing is truly original, but that doesn't mean you can't have your original angle on a particular story or niche. It doesn't mean you can't make the connection between two things that have never been connected. It doesn't mean you can't point out what others have overlooked.
Just because there is a formula out there for blogging success, doesn't mean you need to echo it to achieve your own success. Be your own voice, let others echo you.
