Depends on which section you read. I introduced my fiancee to /r/IAmA and she thinks reddit is mostly about child molesting drug-dealers who fly fighter-jets and rescue endangered species, because they were raised in a polygamist cult family living in the Everest base camp.

To me it's mostly proggit, hastily scanned once every 1-2 days.

Considering all the old slashdot fans had to have gone somewhere, I wonder why...
