I think everything published was very reasonable. But, think about this, suppose you typed a 
catchier post title? I mean, I don't wish to tell you how to run your blog, 
however suppose you added a headline that makes people desire more?

1 in the World is kinda plain. You could look at Yahoo's 
home page and note how they create article headlines to get people interested.
You might add a video or a related pic or two to 
get readers excited about everything've got to say.

Just my opinion, it would bring your posts a little bit more interesting.
