There is a (perhaps apocryphal) story about the art class which was separated into 2 groups - one group worked on a single project all semester and the other group worked on a new project every day. People in the group that worked on a project every day produced better work than people in the "single project" group. My google-fu is weak, so I cannot find the reference.

I'm not suggesting that the Javascript ecosystem is filled with awesome stuff, but sometimes quantity leads to quality.
