Too Many Headlines, Emphasis, Strong, Bold, or Italics
Using the <h1> - <h6> tags for every line of text doesn't make it more exiciting.
It's just annoying looking.
And trying to make an entire paragraph as a heading looks really strange. Good headlines are short and say only what they need to say to cover the topic. Then beneath them should be plain paragraphs. This isn't boring. This is user-friendly.
And the same goes for bold and italics. Use them sparingly, to make a point, not to change the color of your Web page text.
