Komplicado,
Remember, there's no such thing as dipping too much. You dip where you feel you need to dip. With time, you will hone your dipping skills.
As for me, if an article is short (a few columns) I'll state my purpose and read the entire article.
However, for longer articles, the more questions I have, the more I tend to dip. In other words, I start off with a handful of questions, then I dip to find those answers. Inevitably, as I am dipping I come up with more questions, so I go back on another activation pass to collect those answers.
Hope this helps.
Jon
