I always find it a little bit funny when people on a forum are always telling people to search first but whenever a post is brought back from the dead the resuscitator is criticized for bring back a living corpse. In this case though the reason for the resurrection didn’t seem really appropriate....
To me, the most valid reason for not posting to a lapsed thread has to do with the notion of considering a thread to be an ongoing conversation; unlike fact checking, where having a time frame of reference is not necessarily pertinent.
