All three of the above area clearly linked to each other with the same top iframe. In fact they are the same series of sites with the same resources.
That is 94% of the top 100 results is spammed.
If however you go alot broader on the term into something like insurance, hotel, etc the serps are also representative of the amount of sites that exist trying to appeal to the algo.
Relevance in some cases is in the eye of the beholder, and i think in this instance the scale of the term and the prospective size of the community offering it, is key.
