Sure, a lot of his works weren't particularly good, but he tried to encompass a psychological component into his works, which hadn't been done previously. His assertions were almost all wrong, but the fact that he tried had massive impacts on socialism as a whole.

In that sense I see him fulfilling a similar role to Freud: He wasn't correct, but his ideas opened up a new direction, which lead the broader field to actually think about and look into that stuff. Writing against Stirner made Marxism encompass some important aspects, like the historical materialism itself, that might not have existed had Stirner not existed.

Stirner was a pioneer, but also mostly wrong. He was important for the development of socialism and for his time, but is now almost useless.
