Events
I have always tried to promote method development and create method awareness. A couple of things that I've done in this regard are events that get the community involved in creating and using methods. Below are two of the main events that I started.
Method Development Competition: This is a competition where members of the community compete to create a method which satisfies certain conditions. So far each competition has been focused on creating the fastest method. One of the competitions being for 4x4 methods. However, competitions in the future may be about who can find the method with the lowest movecount, fewest number of algorithms, or other interesting conditions.
Method March: During the month of March, the community uses a method other than their main method. This can be 3x3, another puzzle, or another event. The goal is to give underused methods some use and help show the community that there are fast methods besides the most popular ones.
