(But there are some positive changes that can be made)
This is the final chapter in my series about the state of internet fora, and Math.SE and StackOverflow in particular. The previous chapters are Challenges Facing Community Cohesion and Ghosts of Forums Past. Unlike the previous entries, this also sits on Meta.Math.SE (and was posted there a week before here). (As I write this as a moderator of Math.SE, I refer to the Math.SE community as “we”, “us”, and “our” community).
A couple of weeks ago, there was a proposal on meta.Math.SE to introduce a third level of math site to the SE network. Many members of the the MathSE community have reacted very positively to this proposal, to the extent that even some of the moderators have considered throwing their weight behind it.
But a NoviceMathSE site would be doomed to fail, and such a separation would not solve the underlying problems facing the site.
To explain my point of view, we need to examine more closely the arguments in favor of NoviceMathSE.
This is the second in a miniseries of posts on internet fora, and Math.SE and StackOverflow in particular. In the previous entry in the miniseries, I described some of the common major problems facing community cohesion. I claimed that when communities get large, they tend to fracture and the ratio of meaningful communication to noise plummets. To combat this tendency, communities use some mixture of core moderation, peer moderation, membership requirements, or creating subcommunities/splitting off in to other communities.
In this chapter I focus more on Math.SE and StackOverflow. Math.SE is now experiencing growing pains and looking for solutions. But many users of Math.SE have little involvement in the rest of the StackExchange network and are mostly unaware of the fact that StackOverflow has already encountered and passed many of the same trials and tribulations (with varying degrees of success).
Thinking more broadly, many communities have faced these same challenges. Viewed from the point of view from the last chapter, it may appear that there are only a handful of tools a community might use to try to retain group cohesion. Yet it is possible to craft clever mixtures of these tools synergistically. The major reason the StackExchange model has succeeded where other fora have stalled (or failed outright) is through its innovations on the implementation of communition cohesion strategies while still allowing essentially anyone to visit the site.
Imaginary Internet Points
Slashdot popularized the idea of associating imaginary internet points to different users. It was called karma. You got karma if other users rated your comments or submissions well, and lost karma if they rated your posts as poor. But perhaps most importantly, each user can set a threshold for minimum scores of content to see. Thus if people have reasonable thresholds and you post crap, then most people won’t even see it after it’s scored badly.
