I'm waiting for STEAM to accept Bitcoin, who's with me? 
i am right there with you on steam. i was wishing this for over a year now.also inspired by this post about amazon, i submitted a request with their support team a couple of days back, and waiting for respond now
Instead of waiting why don't you call Steam and tell them that people want to pay with bitcoin, that more people will buy more games if bitcoin is a payment option. Maybe start a poll on this forum and then share it with people at Steam. Companies will chase the money...
