To celebrate its first birthday, MobileWhack is giving away 10 $50 Amazon.com gift vouchers! The first 10 persons to leave a comment on this post over at MobileWhack will be contacted by email to receive their voucher.
I think this is a great idea to bring new visitors to your site and to get yourself known even more. The whole mobile blogosphere will probably write a word or two about MobileWhack. As for me, it is a blog I link often to and I recently subscribed to their RSS feed.
At the time of this writing there are still a few prizes left, so hurry up and go!
