I've particularly noticed this on the Not About Food and General Topics boards where people have been commenting on threads that are 5 or more years old. Do we really need to rehash if it's OK to bring flowers to grandma? Or if you should run the garbage disposal before the guests leave? or...?
Yes, there are valid opinions, but commenting on a comment that someone made a decade ago seems bizarre to me. I'm not saying get rid of them, but some of these really ought to be locked after maybe 2 years. Or maybe I've just been around 'too long' (not that I'm going anywhere.)
