I’m not here to enter into a relationship. I just want to buy something. -

The $300 Million Button

I always thought my aversion to forced registration on seldom-visited sites was just peevishness on my part. I remember going to a site to buy a single baseball cap. They made me register. 

It isn’t simply the inconvenience of another step or the assumption of a relationship where I wanted a transaction. Forced registration also forces you to make an unpleasant choice: use (and thus expose) an existing password or make up a new one and have to bother recording it somewhere.
