I agree with this ...& actually the few things which I would love to learn from this post are:

1. Write articles that reference or focus on other bloggers. You will get their attention that way and there's a good chance they will come to your blog and leave a comment as a result.

2. Ask your readers a question at the end of your article.

3. Write about topics that stimulate conversation, such as current events (think politics, news, entertainment).

4. Be controversial with your writing. Have a strong opinion and others with strong opinions will reply to argue or agree with you.

5. Be patient. Sometimes you just have to wait until the first person leaves a comment which opens the floodgates.

(these points are taken from the site itself)
