Why I am getting Irritated with blogger while I write my first blog post?

I am new to blogger,I find something difficult with blogger while i make a blog post.yesterday I make my first blog post.In the process of making my blog post.I find URL structure is the drawbacks of blogger.I can not able to change the blog post title once i publish the blog post.

Why I am using blogger for blogging, Its is easy & I can try using AdSense in my blog.Since I had already used word press in self hosted domain. I found so many issues with Internal server error.

But now I don't find any difficulty using blogger.com. I like using blogger even though It have some draw backs.
