How are results weighted for the search engine in general? It seems to value individual articles vs. sites for specific things more. For example if you search for Minecraft you'll see most of the topic results are individual items, and some of the links are just crazy. The Team Fortress 2 blog (an unrelated game, the only relation is they mentioned Minecraft once in July) ranks higher than official sourced of information? The first link for the Minecraft forum is rank 15, that isn't even a general link it's a specific topic. The Slashtags idea looks awesome, but the search ranking seems terrible.
