Is this a good startup idea? I will not promote

We are a deals sharing platform like Slickdeals or OzBargain, but we share 50% of the affiliate revenue with the deal poster.

My theory is by rewarding deal posters we will bring eyeballs and users who want deals over from encumbant platforms.

I have been an active user of Ozbargain in Australia, and was awarded Ozbargainer of the week twice. For many hours of effort I got 2 free hoodies. The ozbargainer of the month gets $50 gift card and that's by posting 100+ deals a month and basically working fulltime for Ozbargain. I spoke with other Ozbargain power users and some of them agreed it was a pain point for them to earn money from posting deals unless they were a rep for Cashrewards or some other gadget website.
