From my experience, one of the nicest uses of bitcoins that we want to promote is paying people for 'micro-jobs'.
Lets put a new section on the front page of bitcoin.org on the right hand side below Community like:
* Job listings board
The board can be on the wiki or an existing site. One nice one I've been playing around with is, http://bitgigs.com/
Be promoting the use of bitcoins as a method for paying people for small online jobs, we show that bitcoin is a bit more than for buying drugs or speculating on mtgox. It's how I got interested with bitcoins in the first place
by making small amounts of BC for below minimum wage. It's also a neat way to connect people and help the economy flow better.
