3. Do not have a community blog that can be used as a means give each other comments and share feedback.     Blogging ever but I do not have to give comments or feel that no one read, so that  feel with the trauma experience.

4. Do not have a material or material that you want to be in the blog, because it has too many information on the blogs of others and considers himself does not have special expertise that  can be distributed to other people.

5. Mild-nge friendster, facebook or nge-nge-twitter. In addition to promotion of self, we can get a lot of friends, beautiful and handsome-looking. People who rarely get the girl of  blogging.

6. Have been ideal, to search for online revenue, but it is not possible, even rare   people visited the blog. It is through various ways, buying a few books, read the post-post  master’s in business blogs online, but also difficult and can not be put into practice for himself.

7. As loyal readers of course, have no desire to do more. If I read the living  must participate nge-blog as well? Very difficult-so difficult people.

8. Not yet know that blogging can be used as a means to explore personal branding and revenue online. Plus there are no people around with a successful nge-blog. Or not a person the story of  blogging.

9. Rushing to work and every day routines. Keeping for children, his wife and only hard work,  and there is no time especially for blogging.
