How long is the span for grave-digging?
Like, how long is the time span for a topic to be considered dead if it has had no replies in 'x' amount of time?
Kinda confusing, but i think you know what I mean.
It all depends on the kind of thread. If its a sales thread maybe 1-2 weeks and if its a dashboard ask philly questions kind of thread it probably isn't really gravedigging unless its a few months old unless you ask him a decent question.
