These same patterns have been noted for decades in studies of volunteerism, charitable giving, community association, face-to-face support groups, and voluntary religious organizations. They are a consequences of the interaction of human interests/motivations and competition for limited attention/effort playing out at a population level.
Is there really any reason to expect that they wouldn't still work that way? (or actually be made "worse" -- because online environments make the costs of exploration lower, switching from one activity/group to another lower, and the number of alternatives higher).

* "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 The smallest, Galaxy Zoo Supernova (which is no longer active) only drew a bit over 3,000."
