Journal: Submiting to Slashdot

Considering the amount of readers and the amount of submissions to Slashdot i wonder: Is it helpful or destructive to submit stories to slashdot? I mean the amount of man-hours spent in filtering through the garbage to find a story is probably similar to have the editors look for the stories themselves. But then again: i don't know the volume of slashdot subimissions nor the elimination proccess (personally i have submitted 3 stories, all of them rejected....). So i feel compelled to ask myself: Sould i post to slashdot?
