Are FAV's divisible? Can we split them up into smaller units? What does 0.234 FAVs mean?
how about 1 FAV is roughly 15 minutes of time?
Why don't just use 0.25 HRS instead?
There's many people using that unit already: LETS currencies, time banks, villages.cc...
It's usually defined as "an hour of unskilled labor" and often approximated to 10 usd (although, of course usd is not a stable measure of value).
A Note About Hours
In Villages, one hour of acknowledgement is meant to represent one hour of basic, unskilled labour, approximately equal in value to minimum wage. Those offering skills to the community that have taken years of work to develop can and should be acknowledged with multiple acknowledgement-hours for each hour of their time given, according to the value of what they have given in that time.
If you need a dollar value for hours, $10 is a good guideline.
