Why would an obscure link come up first for a simple word? Perhaps you are logged in and it relates to your profile but for generic searches it shouldn't but if it did the link would quickly lose the obscure label anyhow. Maybe the vanilla term isn't so vanilla if those terms are being used that way on the most popular sites.
