Link Bump is social media in action. All of the front
page content is determined by users like
you, not some out-of-touch corporate fat cats. Once a
new link is shared, it's either bumped to the top or
dumped into oblivion. You decide.
I'm guessing it means Google, but can someone in
aisle 5 verify that? Perhaps this is just a way to
generate buzz for zxing, Google's own open source
project for decoding barcodes through mobile phones
cameras.
