Can personality change? Well, it depends on how you define "personality" and on how you define "change."
Certainly manner of behavior and attitudes can change over time as people adapt and "grow," but the deep foundations of personality are genetically hard-wired (we term that "temperament"), along with the first few layers above that (which we often think of using concepts like "character structure" or "constellations of unconscious assumptions/fantasies about people, one's self, and the world"), are highly resistant to alteration - which is where psychoanalysis comes in.
That question was asked in the context of two movies at PsyBlog, who took the trouble to review the best of the psychology blogs: Part 1 and Part 2. (h/t, Neurophilosophy.) I am going to check them all out.
I am not aware of any dedicated psychoanalytic blogs. There should be at least one, but analysts tend not to be compulsive talkers and, when they write, it is always too long-winded and jargon-packed for the average ADD reader. The shrinks on our blogroll are more politically-driven than focused on the art and science of the analytic therapies.
