One problem: users of open source
love oodles of features, no matter how useless. Witness the sheer number of people who admit the primary way they choose a library is the
last commit date and features list.
So if you write a solid library with just the right number of features, then it might get less consideration because you're not always duct-taping over poor design choices.
This is what happens when we glorify Internet Time. It becomes more about shipping and less about quality.
