Might be that Nim is starting to become more used in America. The Nim userbase
has historically shifted quite heavily towards Europe, but some Asian and
American users. The Asian userbase has increased quite a bit, but we don't see
them much around here, probably because of language barriers. But if the
American userbase is growing it could help explain the sudden influx in
"bro"-usage. Next step @daef, correlate with IRC-logs to get more data, and
then find times of day where "bro" is most heavily used. Judging by timezones
we could probably estimate where the usage is coming from.
