In either case, whether searching or browsing, there are hidden gems in old newspapers if you know where to look. Here are 6 great examples:
"Positions Wanted" section can be very useful. In this example, I wanted to know my grandmother's occupation.

The moral of the story is - look beyond obituaries and other vital statistics such as marriages, divorces and births. There are lots of "hidden" sections in old newspapers that will give you clues about the lives of your ancestors. And you might have to employ browsing of these special sections to find them if searching for names doesn't yield you the results that you want.
