This from Ars[1]. Sound familiar?
- "The top 10 percent of contributors end up supplying an average of about 80 percent of the total effort put into these projects."
- "Most people who show up to check out a project never return. The most compelling projects still saw 60 percent of their users stop by for a single visit and never come back; the worst case was an 83-percent rate."
- "The topic of the project also seemed to have some effect [on participation rates]. The biggest project... lets users sift through Kepler telescope data to search for exoplanets; that attracted almost 30,000 users in its first 180 days. The smallest, Galaxy Zoo Supernova (which is no longer active) only drew a bit over 3,000."
