There is no Bitcoin economy and there never has been, it's all lies and deception to justify higher prices in the minds of a few bubble driven speculators. ASICs aren't an economy. The only thing we have are Silk Road and Satoshi Dice.
*shrug*
Whatever perspective suits you, I guess. The Bitcoin community continues developing, regardless.
Aside from that, all other economic indicators I know of like bitcoinstore.com, Humble Bundle sales figures, Reddit Gold figures etc. suggest that Bitcoin simply isn't a currency. If anything besides a store of value, it's a USD proxy to buy certain goods.
What does it matter that it's not a currency? Gold isn't either, yet it's still valuable, and won't be going away anytime soon (despite decades of anti-gold propaganda, no less.) Why is it that if there's not an overwhelming abundance of goods and services available solely for bitcoins, something must be wrong?
I do think that Bitcoin can work simply as a store of value, but actual uses would be a boost, and I'd suggest to look for uses where Bitcoin has not only an advantage, but uses which without Bitcoin would be impossible.
It's a digital currency. If you ignore it's key features (pseudonymous transactions, limited amount, decentralized,) then any other digital payment system can do what it does just as well, better in many cases. About the only thing that can be done that's impossible without Bitcoin is storing wealth anonymously without needing a third party (EDIT: and pseudonymously sending it across the planet without a middle-man.) That's it, it really has no other advantage. Because that's the one primary feature set it was designed to have.
The inevitable conclusion is, there's not going to be any trick or secret key, no undiscovered catalyst to accelerate the growth of the Bitcoin economy. Other than in the area of anonymous wealth storage (which doesn't require any real infrastructure,) it's just going to have to grow at the same slow, steady pace as anything else.
(EDIT: Also, private transactions are a potential, Bitcoin-only growth area, I suppose; the tricky part there is that we live in a society where most people don't value privacy very much, except those trying to evade societal controls. Guess that means we should be focusing on North Korea as our growth market?)
