The eventuality of the content powerhouse - internet

I go online and try and look up something...lets take a product for instance...go to about 50 sites which have the same product and write things about it...what do i do...what do i believe...

Simple idea...this happened in everyday life too...with other offline products...
lets take light bulbs for example...there were a lot of them...eventually there was one neutral company which tested it...tested all the light bulbs and then gave it the ISI mark...(India)..so we have some1 to believe

So basically there is one firm which tells me that this company makes bulbs which have been tried and tested...

Exactly what I believe will be a necessary eventuality on the internet...A site which standardizes the content of other sites...

Like Verisign stamps its logo on a secure site...this entity will stamp its confirmation on information...
