The context got a bit messed up due to the way HN ranks comments but _giu is referring to the experts exchange answer pages that are returned from a Google search.
If you receive a search result on Google that points to an EE question page, you can see the answers at the end of the page. EE tricks casual visitors into thinking they need an account by putting a long list of things at the top of the page and the real answers all the way at the bottom. This way Google ranks the question/answer but people think they need to buy an account.

note If you visit the link directly, the real answers disappear. Yet another sneaky EE trick, this time preventing bookmarking/direct linking.
