Characteristics
The extraordinaries:
"Micro-volunteering has four defining characteristics:
1. Convenient. It's volunteerism that fits into your schedule when you have time - typically (but not necessarily) via an internet connected device such as a mobile phone or personal computer. In practice, to achieve this level of convenience, there is often no training or vetting necessary.
2. Bite-sized. Volunteer tasks are broken into small(-ish) pieces, so that you can complete a task in the time that you have available (whatever that time may be).
3. Crowdsourced. The nonprofit that needs help asks a large(-ish) group for assistance. Micro-volunteers who have the time, interest, and skills (ideally), and who may be previously unknown to the nonprofit, do the work.
4. Network-managed. The time demands of the manager (e.g. a nonprofit staffer) are reduced by distributing as much of the project management and quality review as possible to the network of micro-volunteers. This work management method differs from a top-down model of project management." (http://blog.beextra.org/2010/12/a-definition-of-micro-volunteering.html)
