Outsourcing login and over-reliance on Facebook

This is exactly my point in this thread: http://news.ycombinator.com/item?id=2295834

There is no way I will sign up for an account on FB for content/to comment on content from other third party systems that are too stupid to have a site that is not sucking from the teat of FB to such a degree that they dont know how to allow either anon or registered commenting.
