I am writing about the service that Flattr provides, and whether it can be done better. Flattr provides a way for people to make "micropayments" to each other. How it works: people put special links on stuff they made/own/want appreciated, and when people click those links, it gets recorded as "spend some money on this at the end of the month". Every month, the clicks are tallied and the amount you choose to spend is divided between the things you clicked on and sent to them.
I see two problems with Flattr:
People must have accounts with Flattr for it to work.
Flattr collects fees on all transactions.
Is it possible to let people send financial appreciation to each other for things on a large scale without running into those two problems?
