Yahoo! is known for having a comprehensive design patterns library providing patterns for a variety of use cases. Their newest pattern aims to tackle Digg & Reddit types of scenarios in which a user wants to “promote a particular piece of content in a community pool of submissions”.
This pattern has come to popularity recently (most notably on link-popularity sites Digg, Reddit, Newsvine, among others). Such systems for collective choice are a good way to promote community participation, and provide a low-cost means for surfacing popular content. Note, however, that popular content does not necessarily equate to quality content, so no promises of content quality should be made.
Use this solution when
- Users in the community have the ability to submit content to a ‘pool’ of resources.
- Some democratic form of judgment is needed, to allow the community to compare the subjective quality of one submission to another.
- A sizeable-enough community is required. Ideally, popular submissions in the pool should receive significantly more (dozens, hundreds?) votes than non-popular ones, in order to make comparisons meaningful.
In addition to the new pattern, Yahoo! has now introduced the concept of a pattern gallery which, in conjunction with diagrams and templates will allow developers to see actual examples of specific pattern usage via a Flickr gallery. The “Vote to Promote” pattern is the first to use a pattern gallery.
