I have one notebook on Evernote called Knowledge Base, but the problem maintain it. I mean, everytime I have a problem first I go directly to Stackoverflow and almost always there the first result gime the answer, so I don't put it on notebook.

But this notebook became useful to store not common errors that I couldn't fine solution on web. Normally it is related to some new tech or very specific scenario.

I don't see a problem with this. If Google can easily show you the answer to a problem, use it! The Evernote notebook is a good last-line-of-defense that captures things you really struggle with - or issues that require a solution with multiple parts.
