It's all existing bitcoiners buying bitcoin mining gear for bitcoins. If there were no such thing as bitcoin; these transactions would never have happened.
To get justifiably excited about this sort of record breaking announcement we would need to see it being made up of thousands and thousands of small, every day transactions, that would have happened whether bitcoin existed or not.
I get more excited about people buying baklava (sorry if misspelled) for bitcoins than I do about people buying mining rigs.
I love Baklava - where can I buy it for BTC?

If that's your site, check your emails for an exciting query from Gareth regarding international shipping and expect a bitcoin payment soon afterwards via what I presume is the standard bit-pay button (otherwise it looks a hell of a lot like it).
