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The smallest, Galaxy Zoo Supernova (which is no longer active) only drew a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."*
