I'm #2, I only speed when I'm waiting for new puzzles or broke, which is almost all the time.There are a few different type of cubers that I've noticed:
1. The competitive ones - you don't necessarily have to be super fast, but to have fun competing and meeting up with other cubers
2. The collectors - These people solve mostly for fun and 'some' go to competition, and collect a lot of puzzles, and even make their own inventions.
3. Closet Cubers - These people know how to solve a cube but have little to no knowledge about speedcubing and the WCA.
