I don't use SO to ask questions any more, but it's really good for searching stuff you already know but don't like to remember, like if that method used camelCase() or under_score(), what the annoying workaround for that little quirk in the framework of your choice was, etc.

I feel beside the new stuff that comes from new FWs and languages most questions seem to be answered. Therefore starting to focus on long term quality is not a bad thing.

Most of my recent work in SO was also not asking questions but correcting/connecting answers that are already there.
