Every few months a plague descends on Usenet called the spelling flame.
It starts out when someone posts an article correcting the spelling or
grammar in some article. The immediate result seems to be for everyone on
the net to turn into a 6th grade English teacher and pick apart each other's
postings for a few weeks. This is not productive and tends to cause
people who used to be friends to get angry with each other.
