    Have you ever considered about including a little bit more than just your articles? I mean, what you say is fundamental and all. But think of if you added some great images or video clips to give your posts more, “pop”! Your content is excellent but with images and video clips, this blog could definitely be one of the best in its field. Very good blog!
