I've participated in a few discussions about this. I also once posted one and in it I had gathered a few links to previous discussions on the topic. I am only posting it here because, since it is my own submission, I am aware it exists and I can find it readily. Hopefully, it is a place to start.

A search of the site will turn up other discussions on this topic. I mention that because this type question often does not generate good new discussion so a look back is sometimes your best hope of getting some insight. You might also search on my user name and "chicken and egg", since that might lead you to a few posts with lots of links gathered where I commented but was not the submitter.
