I've often wondered if it would be good to snip out the offtopic content once threads have cooled.
Sometimes threads start with a question, get discussed and answered. Then they drift off topic and rattle on for a while. The poor newbie (or vet trying something new) searching the archives is reading all this offtopic stuff at the end of the threads hoping for extra info and basically wasting their time.
This should only be applied to threads that have been inactive for a long time and are unlikely to be revived.
Maybe it's a terrible idea, what do you guys think??
