Blogs are here for that reason - we don't have to make a blog entry specifically about weight loss or anything else. A blog is where you post your personal thoughts, experiences, or anything else you want to post.
Sometimes sharing your feelings is the only way you can free yourself from the "drama". That saying about how the truth will set you free - well it's true.
I'm following this blog because I'm interested. Not everyone will be interested. The solution is to just not read it if the "drama" bothers you or doesn't fit your ideas regarding relevant posts.
