I know that Reddit, after months of enabling Bitcoin as a payment option, still only got 3% of their entire revenue in Bitcoin [2]. I like the concept of bitcoin but as of now, it seems like many of these initiatives are launched by businesses to get "tech people" interested and to make news about their business. That's not a terribly bad thing though for bitcoin because businesses are still adopting it. It just would be nice to see Bitcoin used more than 2.5% of the time.
