While looking at my own (ad-free) blog I saw amitabh banchan selling me life insurance. I don't want my readers associating me with this: http://www.hkyantoyan.com/wp-content/uploads/2012/09/AB-bina...

Switched to https shortly after.

And also from them tracking what you read to give you specific advertisements.

Man, it's really all about advertising these days...
