For Shamy Lovers: The progress of their relationship, past signs and what may come forward in the future

Hello, I happen to be a Shamy lover. I love to read all articles about them, analyses and all that. So tell me what is it about them that you love. Maybe you can share with me your own analysis about them. By the way, please don't post something like I don't dig the Shamy, I prefer Sheldon and Penny stuff. Also please don't post to bash this pairing. This one is only for those who love them, and I don't mind reading about their friendship as well, this is not necessarily focusing on the romantic aspect :)
