Startup Idea : Make misleading Information on the Web visible

The web is more and more a place of misleading Information. Wrong product evaluations and comments, Blog-writer that give recommendations to earn from an affiliate programm, companies that set up product comparisons to place their product on top, hoaxs etc., misleading statistics. Each Web user should have the possibility to annotate, comment and rate the trustworthiness of an Information. There are great tools such as WOT, diigo, reframe it. Now it is time to establish a safe and fact based online experience to all. This is different to WOT, as I want to mark the misleading Information rather than the whole Website. In example, if a Blogger forgets several other tools to mention, everybody should have the possibility to make other aware of this. There can be different solutions and I ask to share your ideas and may be we find a solution..
