"using your personal data to tailor results", true, I don't like it either. When we are targeted, we always see the outdated ads from 9 out of 10 websites we visited but don't like to re-revisit.

So "pull" is more favored than "push". See the book:

"Pull - The Power of the Semantic Web to Transform Your Business" by David Siegel.

But I do like personalized information storage. Maybe you want to reference to the blog post:

Why do we need the Private Web? http://bit.ly/1c2DzN6

" When we are targeted, we always see the outdated ads from 9 out of 10 websites we visited but don't like to re-revisit"

this is very true. You have just listed a billion dollar idea. If I search for an adidas shoe or just go to a company website then I start seeing ads related to those just visited sites - how boring. Retargeting just seems to be plain stupid instead consumer should be showed more variety

Yes, "more variety". Give you a big 5! We are like-minded.

But from an idea to a popular web application has long way to go. We just kicked off our first Kickstarter project to spread the message out here: http://kck.st/JNqv8z

Some people gave me negative points, maybe they don't like the BingoBo.com website because it does not provide enough data. Please read today's update here: http://kck.st/1exzNy6

Enjoy!
