There was Web 1.0 where just getting online was important.  Web 2.0 came and started the community and knowledge sharing aspect of sites.  Web 3.0 is in full force by delivering the appropriate content direct to you. 

Blinkx is a new type of 3.0 company.  Where ads can be placed on sites based on content or visitor behavior, but what about video?  Blinkx solves that by using contectual models to add ads to videos. 

Seems cool, they can overlay the ad or keep it outside.  You get paid for the click.  Kinda cool.  Trying it out and will report back on how it works.
