Ask HN: Would a product feed in your app help you? (Startup idea validation)

I'm really interested in the problem of delivering personalized product feeds in Mobile and web apps to customers as part of my startup. I was considering starting with giving the ability for developers to drop in a code snippet, allowing users to customize what they want to see, and an easy way to publish new feed items.

I'm wondering would you use it? (why or why not)

If it would be a product you would consider paying for?

Thanks so much!
