I'm looking for help with a Stack Overflow application that could do the following things for me:

1. Extract the top voted questions at a given date and tag
2. Extract the answered questions of some given user

Recently, I have created an opensource APP with scrapy-python and PyQt that could extract and collect the top voted questions at a given date and convert them to PDF.

I put it on Github, but as it's in elemental level I think it could be better and developed.
So I ask users, if they have any experience on related subjects and technologies, to feel free and help to improve it! ;)
