Timebanks are an interesting phenomenon. The basic idea seems to be that one hour of my time is as much worth as one hour of yours. So if I work one hour, I can get one hour of work from someone else.
The only Swedish timebank I know of is called Timevillage (if anyone knows of any other, please post a link in the comments). People offer anything from business coaching to "help to find love".
Since I want to see how it works I sent a message to Bianca Lovecraft about a pole dancing lesson. But she hasn't answered in a month... :-(
Now I'm hoping I'll have better luck with the kizomba teacher. Kizomba is an Angolan dance I had never heard of before logging on to Timevillage. Judging from this youtube clip it doesn't look too complicated, as long as you get that basic move right...
