I wouldn't expect this to happen much, but after reading about the R-Mob hitting the SO servers recently with their questions, I thought I'd go and check out what R is. I found the question "Sample Code for R?" and was giddy to see what I'd find.
The accepted-answer, with 6 up-votes (last I checked) is a link to a blog (http://www.climateaudit.org/) that occasionally may discuss R. Seriously? This is the accepted answer for a question asking about "Sample Code for R"?
This is sad, in all honesty. I wanted to learn about R, and instead I ended up on a blog discussing the surface-temp of Africa.
It got me wondering, what is to keep 2 people from asking questions, providing nonsense answers for eachother, and accepting their friend's "solution"? We spend a lot of time thinking up ways to prevent a single user from gaming the system, but this type of senario seems like we should start considering small groups of 'gamers.'
