If you're interested, I'll link to a social networking group with an interesting spin (in beta): your AI counterpart.
This particular social network has an AI component that learns how you interact with their systems; it learns your interests through how/what you post, when you're most likely to post, etc. Then even when you're offline, your counterpart will be active on the social network. As you train your counterpart, it learns how to more closely imitate your online habits.
This is a more 'intelligent' than chat bots or spammers, and indeed their uses are rather different.
Personally, I think the idea of a counterpart intriguing. At the philosophical conclusion, you'd have a 'digital' (AI) you, with real experience interacting in your social network. Implications of mass adoption would be...slightly freaky.
