I know promoting has always been a big challenge for game developers. We are currently developing a platform that could potentially help iPhone game devs promote and increase exposure of their games. I would really love to speak to some of you and better understand some of the promotional / marketing challenges you face in more details. I'd also love to gather some feedback from you on what we are doing. If you have some free time and wouldn't mind a quick conversation, please PM me or Email me at frocer [at] yahoo [dot] com Thanks very much!
Actually we're thinking of the same thing too. Maybe a partnership of some sort might be of interest to you. If not, I'm definitely keen to sharing our challenges.
