Welcome, and enjoy the forums. I am assuming you are a fan of Ayn Rand or at least have read Atlas Shrugged and it formed a mental impression in some way.

Wittgenstein is always interesting, and there is a lot of work being done on problems he discussed. I am sure, as well, that you will find much of interest in reading the many dialogues in the threads, and encourage you to become an active participant---in a way, you can't understand philosophy until you attempt to do it, and the practice of thinking and then writing clearly about a topic is good practice.
Welcome to the Forums,
