A while back there was a post in general discussion forum I think about something similar, robotic hug yourself machines or something. I think it's really sad actually.

I mean I love robots and all... I do, nerdy like that in the basement. But way to phase out human contact. We already phased out real life conversation, now we have phased out phone conversation ( the enjoyable kind only ), and now we are working on phasing out the need for human contact through touch. It's sad, and sad that there is a need for this.

Ya and then what if you are not active on there, no account, or have crappy friends... no hug for you! Gawd humans are so smart and stupid all at the same time.

I'd hug you DH!
