You should look at with other set of eyes, like, you shouldn't be looking for a media channel for the sake of being a media channel - which producthunt is: a platform with the an audience of early adopters, entrepreneurs,and tech enthusiasts are... like they say "It's a place for product-loving enthusiasts to share and geek out about the latest mobile apps, websites, hardware projects, and tech creations."

There's the possibility that it's not the best place to focus your efforts on.

So the right answer is actually, everywhere, within the legal boundaries of course - and you shouldn't be disappointed with this reply, because it opens you to a whole world of possibilities.

You should rephrase your question like: This is my product [explain it or show it], and this is my audience (or potential audience), how to I get this product in front of this audience, with this budget (from 0 to ...).
