My dream career is in Psychiatry. I am not sure as to what population I want to work with yet. I have found some great blogs in the field:
1) http://mancpsychsoc.blogspot.com/

The Manchester Psychiatry Society Blog takes a playful approach to the science/medicine of psychiatry. The articles are fun and colorful but also give you great information.  

2) http://real-psychiatry.blogspot.com/

This blog is written by George Dawson, MD, DFAPA. He posts things about his personal life, medicine and science, and also psychiatry.

3) http://carlatpsychiatry.blogspot.com/

This blog is very helpful for people in medical school or planning to apply to medical school. Its posts are usually centered around the mechanics of being a medical student.
