I got into a public dispute with Max Keiser and his psychotic followers about this and people said it was semantics. There are three distinct moments: 1) Accepting Bitcoin (kudos to BitPay and Coinbase for making it so easy!), which is primarily a cheap PR move; 2) Having real commerce going thru this channel (i.e. volume as USD equivalent) - everybody seems shy about it; and 3) Truly accepting Bitcoin into a Bitcoin wallet!
