[Disclaimer: A write-up of mine is one of the current front page items thanks to second chance, as well.] It's a great feature, because, as long as you want just to share and do not care too much about your karma (you'll lose half of it), you don't have to manage submission dates, like figuring out, if the right audiences will be present right at that moment to pick it from the stream of new posts.
Shout-out to dang & Scott, who are doing fantastic work!
