The "What are your ___ threads?" I´ve been doing this past week has spread to some necro-bumping. Obviously for the unresponded or popular threads it didn't matter much. I even saw it as positive for the dud threads. I also saw it as a nice way to see which threads did what, and as a way to look back.
Still there has been some collateral damage done by mcnol012, in which he has necro-bumped quite a few threads linked there.
But they will fall down.
Just have patience.
