As it could be very helpful that we can extract the questions that we like from Stack Overflow, I'm looking for a application that could do such following stuffs for me:

 1. extract the top voted questions at a given date and tag!
 2. extract the answered questions of some given user! 
 3.   ...

Recently I have created an [`opensource APP`][1] 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][2], 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! ;)
