Yep. It'll normally get you the wrath of the moderators as well, unless your post has gone unanswered for a decent length of time, or you offer up additional information/details you may have omitted.
It's also occasionally used to propel something helpful to the top of a forum prior to it being stickied. IE if there was some major problem with WD harddrives and someone found a fix, users might begin 'bumping' it to ensure others with the issue quickly find the solution.
