I recall just the other month when there was much bemoaning and gnashing of teeth about how former reddit people were showing up here in more significant numbers than the general trickle previously and the comments along the line responding to new users leaving 'lol' as the entirety of the comment "this is not Reddit - comments and contributions are expected to be significant or constructive." And if HN didn't try to retain its identity, then we'd be adapting to people leaving "LOL" comments and extended pun chains. Is that gatekeeping?
