I'm less of a Wikipedian than just about anybody who contributes here. My only value is in the development of thought about Wikipedia as viewed from outside Wikipedia. Despite this I know more about Wikipedia and have engaged Wikipedia and it's denizens more than anybody I actually know. Not even close. I'm out there in far end of the normal distribution of...well normal people... in terms of experience with Wikipedia. Still, I sometimes watch the parade of things I don't care about in the discussion of personalities and dramas on Wikipedia with bemused detachment.
This has led to a minor insight into the nature of community dysfunction. The received knowledge concerning Wikipedia's community is that once there was a Golden Age in which a true consensus based community evaluated users based on the merit of contribution. This Golden Age was doomed because this utopian state of affairs does not "scale up" to the level now reached by the project.
This never happened. Wikipedia is actually a village of no more than a couple thousand participants on the level that that makes people believe they are part of "the community" Almost all of the millions or tens of millions of "user" Wikipedia have no ongoing relationship or investment with the project. For a "reputational economy" to function among a group pseudonyms a couple of things are required. First the membership must be stable over time. This is mostly not a problem on Wikipedia, although that might change. Second, the number of participants must achieve a level large enough that only the users record of contributions not alliances, vendettas, and ass-kissing matters. Such an economy would work only if each exchange between participants resulted in record of relevant information only. Information not relating to the goals of the project (eg about "social networking aspects" ) will act as a substitute medium of exchange. Like currency in any economy, the bad will drive out the good.
Bootleg social networking currency can only retain value as long as the project scale remains limited. In a project that truly has millions or tens of millions of participants repeated interaction between the same participants becomes too rare to hold value. The only currency that then matters is that relating to the project's manifest goals.
This needed scale has never been achieved on Wikipedia, which functions very much like a small town in which everyone is into everyone else's "beeswax" on a level that is just plain creepy. This might be because only a very small segment of the population is susceptible to the lure of Wikipedia. It may also be because the "Old Timers of the Golden Age" keep raising the bar to ration access to maintain their positions in the project. In either case the result is the same: Wikipedia is not the the bastion of consensus and merit it hoped to be, but instead it is a hopelessly dysfunctional community. The community that does exist is an extremely skewed sample of the general population that likely contains many systematic distortions and even an overabundance of social pathology.
