There seem to have been a lot of 'person profile's on HN recently. Might anyone know if this is a summer, current journalism thing, or just HN's recent preference?
HN trends happen regularly. Right now it's profiles, in the past it has been military aircraft, biology, whatever.
It's pretty neat and seems to work well - waves of variety without the segregation of something like subreddits or the chaos of a completely theme-less forum.
Ideally, I'd have a "More like this" button that would identify recent submissions belong to the same topic cluster.
