Ask HN: Okay to post iPhone apps?

I see a lot of people asking for reviews on their web apps. I was wondering if it's okay to ask for reviews/promote an iPhone app/game that you have developed.

I just released my second iPhone game and it's picked up a lot of momentum on the app store, so I figure posting it here could help me out a lot. I would like to know if this practice is looked down on by the HN community.
