hadley, I love your book, and I learn a lot from your preferences in R packages. Now is there a general source for determining the "best" packages for various tasks?

CRAN has task views, but they are long lists and don't clearly show popularity or feature matrices. There are just so many options.

Im thinking something like https://djangopackages.org , for example see https://djangopackages.org/grids/g/commenting/
