What is the real problem on having duplicates? They are only 1 KB files.

Having duplicates with different names is even better, and helps to find it more easily in the future: let's say I have bookmarked 2 times this question https://stackoverflow.com/questions/19165259/python-numpy-sc...:

1. "python numpy/scipy curve fitting"

2. "scipy.optimize.curve_fit question"

Later I can find it with query="curve fitting", or I can also find it with query="optimize". So it increases the chance of me finding it again :)
