I was buying a lot of article writing service (0% payment fees is nice!)
I shipped several orders from international customers in my http://store.gifti.us and accepted payments in bitcoins (0% foreign transaction fees is nice too!).
I bough steam codes.
I built somewhat profitable for short period of time site - http://betco.in and used some profit in bitcoins to pay for development work on open source project.
EDIT:
Bought, just like few other visitors, articles in PDF at http://ubitio.us. This is also project of mine and I am going to contribute it to open source soon, so just another bit into bitconomy.
And I am working on two other projects involving products/services and bitcoin :)
This is just what came in to my head right away...
I envision a bitcoin meme: 0% fees, 1000% volatility :)
I am converting to usd only part needed to pay suppliers and rest leave in coins for now. Agree, income is fluctuating. But I am ok with it since so far I did not see technical issues with bitcoins itself.
But you are right - as I said below, huge fluctuation (although, what time period you used for 1000% fluctuation claim?) is a problem. And I will welcome stabilization at any level. Although market is too small to be stabilized soon.
1 & 2 - were existing pieces of software which are actively developed further.
3 - started from scratch.
All of these are open source. Technically anyone can clone github repo and follow instructions to spawn copy of this project.
Project licensed under AGPL which secure all future changes into it will become open sourced as well.
However, it fails to use bitcoin as a currency in the sense that other stores use dollars as a currency. The prices on Silkroad are adjusted to mirror the USD->BTC exchange rate dialy. And, I would suspect that the majority of the users are buying bitcoins to buy goods on Silkroad, and that venders on Silkroad turn their BTC back into USD often. These two use cases don't support BTC as a viable currency. It is being used exactly as detractors presumed: merely a way to launder money.
Anyway, a currency that people buy to use in particular markets is possibly a way that money got started in the first place. People traded for a currency to use in a (physical) market and then traded that into different stuff that day. Eventually, as things stabilized they might have been happy holding some money.
If bitcoin became commonly used as a way of transacting, but not of storing value or denominating prices it could still be a good enough starting point.
Even if the only markets in which it was "commonly used as a way of transacting" were illegal ones, as a means of money laundering? Is that really a "good enough starting point," a way for drug dealers to clean their money?
All currencies are valued against each other, it is no surprise to see the dollar value used most frequently to determine value, since dollars are the worlds reserve currency.
My opinion is that bitcoin is probably ahead of its time, the technology is amazing, and could be used in many different ways, and I am not yet ready to count bitcoin out just yet.

Like, I know the site exists, but how many people here know people who have successfully conducted commerce on it?
How are they keeping themselves from being exposed?
It's the main driving force behind the price of bitcoins on the public exchanges, which makes for a rather novel opportunity for a market-moving attack I'll leave as an exercise for the reader.
Unless they only buy virtual goods, there's a trail to follow.
There's nothing inherently linking the two transactions of "X bitcoins transferred from wallet #1 to wallet #2" and "Y USD transferred from Bob to Joe" - with sufficient care and redirection, you can make it very difficult to track down exactly where the bitcoins are being traded for real money.
Then, they have to setup a trap in which the recipient knowingly takes delivery (and there can be no other way than the recipient signing for it, or else it would be entrapment or just mis-shipment, which is just as common) and catch them. All for a person who bought a small packet of drugs.
I think the Feds even consider such a thing a lost cause.
While there is an iTunes store in Germany, some of the apps aren't available (e.g. TV Station apps that I could use with a VPN) and with the current euro/usd ration, the US store is cheaper.
Sorry to hear betco.in's going down -- StrikeSapphire.com will stick around no matter what the price goes to, because it's just a good, efficient way to take bets, process payments, and pay people out.
