This seems interesting, but how does it work? An advertiser pays for a slot on your site? But what is the appeal for a user to be on your site looking at ads?
Correct, advertiser pays for the slot ($1-10) and the ad will be displayed on a billboard, which rotates through other submissions. You can filter it down via tags.
Eventually, users can subscribe to daily/ weekly/ monthly newsletter with their custom filters (tags) to get promotions for the tools/ services/ products they are interested in the most.
I remember the Million Dollar Homepage which was almost 20 years ago but the question is still valid. This is different, apparently less novel on the surface (selling typical slots, not pixels), so what or who is it for? I am curious too.
