guycook's lament is about the findability of the project for laypeople, not about its interface. The interface is not an issue when laypeople can't find the project in the first place.
I don't know how they account for people clicking multiple links in new tabs. My guess is they reorder links sometimes so that users that click multiple links cancel each other out. They just try to maximize the probability you will click on a link and not come back to the search page.
Not saying they don't, but it seems unlikely and I'd be curious to know if this can be confirmed.
