I believe PyPy folk think it ready now, at least for some uses. 
Speedwise, it is more or less is now comparable to CPython, winning some

Depends on whether your goal is personal (learning, fun, use) or 
usefulness to others. For the latter, you *might* do better to help with 
an existing project, such as Cython or Dufour's ShedSkin.
