Frequently I have to barge through ten screenfuls of code that don't work before I finally get to a correct answer.
To add insult to injury SO doesn't allow questions about many important topics such as "how do I eliminate the wheat from the chaff for all the libraries I could possibly use to do this?"
It might be 2035 when they finally add parenthesis to all the Python code examples so they work in Python 3.
The idea was to get the definitive answer as in Wikipedia. It was a good time when SO came out, afterwards it degraded in quality like anything else in universe.

I have better things to do than labor for the wonks-run-wild at StackOverflow.
