You can call anyone for advice / feedback on Clarity, you're just not allowed to pitch. So technically we support it today and many people already do this.

It's call Customer Development.

As Dan says, ( and he should know) This site is not really for that. You could develop relationships by giving advice on subjects pertaining to your business, but i see that as a byproduct.
Use LinkedIn and other social and business apps to reach out and engage customers.

I use Twitter for Customer Development as well. You'd be surprised how well Twitter can be for finding potential customers and you can reach out to them by a simple direct message.

I can share with anyone on how I use Twitter to connect with my target market.
