Nucleic Acids Research, 2012, Vol. 40, Database issue D1275 Figure 3. (A) Visitor statistics from Google Analytics for 11 August 2010–10 August 2011. The numbers of visits that are the n-th visit for a given user indicate users who return to EcoliWiki multiple times. Note that the number of users who visited n times is included in the count for users who visited fewer than n times. Thus, each bar is for the number of users who visited n times or more. (B) Distribution of user contributions to EcoliWiki, excluding project employees. Increasing the participation in editing will require new ways to make editing align with the other incentives that determine how scientists allocate their scarce resources of time and energy. One potential mechanism is to encourage academic scientists to incorporate editing EcoliWiki into teaching. A section of the wiki on Educational Resources can be used to share materials and methods for this pur- pose. We have also developed wiki extensions to allow instructors to more easily track where their students have edited EcoliWiki. Future directions for EcoliWiki will also focus on increasing its utility through further integration with other tools via the PortEco project (http://porteco.org). In particular, we are working to improve the connections with our PortEco partners, EcoCyc (3), the PortEco instance of the Stanford Microarray Database (44) and PANTHER (45) in ways that optimize their synergy with wikis. For example, while it would not be appropriate to have community editing of data from a published tran- scriptome experiment, community curation of the meta- data associated with that experiment can be valuable for analyses across experiments from different labs. Similarly, while it might be difﬁcult to devise a system for direct community editing of phylogenetic trees, community
