A dentistry blog written by a dentist doctor Eddy Heriyanto from Medical Department Universitas Hasanuddin Indonesia. I like this kind of niche blog written by a “niche” person. I like also the fact that he writes his true identity and his educational background. His writing may be scientific even without revealing his educational background. By doing so, however, his writing getting more credible. If you have problem with your teeth, go to this blog or consult the doctor blogger.
