Can you name some of those services that spring up? So far i have not been able to find anything that would make use of Bitcoins in an interesting way.
Given the ease of BTC as an electronic currency, there are not too many unique services. BTCSportsbet is cool and CoinPal allows you to buy giftcards, etc. but nothing ground breaking.
Witcoin is interesting/unique because it operates in this kind of "micro-economy" space that is disallowed in other currencies because of transaction fees and the hassle of setting up paypal, etc..
Bitcoin is perfect/preferable for very small transactions. This coupled with the fact that there simply aren't many Bitcoins out there probably points to unique ideas cropping up in the micro-micro-economy space.
Check out https://en.bitcoin.it/wiki/Trade for a complete list of services.
There is a lot of cool stuff in the pipeline coming out in the next couple of months. But yes, there are missing services in the bitcoin economy, it's a young economy, which is all the more reason to jump in.
The site mentioned in the article is a unique use of bitcoins. It makes it possible to give as you live http://witcoin.com/charities
The big upcoming service that will be able to utilise bitcoin is nfc which google is bringing to android. They recently introduced a bitcoin library so it will be a possibility at least.
