If it's not nofollowed, any sponsorship link could well be worth $5 especially after the site's been linked from here?

At some point, the Million Dollar Homepage seemed ridiculous, but once it started getting press (and thus pagerank), links from it increased in value. Was nofollow a common thing back then? There would've been a sweet spot when it was notable enough to get press, but not enough for your link to be swamped amongst many others.

Assuming there's still traffic beyond the initial 800 HN visitors, $5 for a couple thousand more targeted viewers isn't ridiculous.
