Where is organic farming applied?

Are there any good examples of the "appointment (farming)" game mechanic applied to web services?

• Appointment game mechanics : letting people make appointment and come back later to "harvest". Because the compensation is delayed, the user needs to come back later to justify her time there. If she doesn't, she has just wasted her time committing something to the service.

• Answer:

  I'll assume that you're talking about requiring a player return to the game within a particular time window for a reward, and if they miss the window then they experience some kind of loss (loss of investment, loss of opportunity). Daily Deal sites such as Woot and Groupon. If you miss that day, then you miss a deal that might have appealed to you. Auction sites (e.g. eBay) fall in this category due to bidding behavior in practice. That is, many people don't want to signal their maximum bid beforehand, so they come back near the end of the listing to set their bid.
