I'm not entirely sure how good this idea is, but basically there have been a few times here where, as a by-product of answering/asking a question, I learn about something fairly new in statistics that I wish more people would know about. Something I learned about this year was this method of making model predictions with SEM and another method I learned about a year or two when it first came out was the
partR2 package for mixed models, which again came about randomly from asking questions here and on SO.
The idea I was considering is having some kind of mega-thread or wiki that updates new advances in statistics that are notable in some organized place so people who casually browse can keep themselves up to date with what is considered cutting-edge. Best would be having the statistics explained in a simple way rather than just linking whatever, but any information is better than none. Some of these things get lost under the mat and it would be good to have a resource to point people to if they want to learn what's out there. I also realize that some of these things can simply be looked up in places like Psychometrika, Journal of Statistical Software, etc. but the point is to make these techniques more accessible to a wider audience.
Feel free to shoot this idea down if it has been suggested before or is infeasible. Just a thought. I found a somewhat similar suggestion here.
