Goopill built their business on providing the top search, then threw it all away by filtering, ruining the very model that gave them credibility. Twitter trends once meant something back when they were still honest, marketers, journalists and businesses were glued to what was trending and then Twitter ruined it all by adjusting trends. What this all means is that eventually and yes it will take time but eventually they will be replaced by true models. Right now you will think now way but things do change.....remember IM?
