  Code reviews in the 21st Century

There's an old adage that goes something like: 'Do not talk about religion or politics'.  Why?  Because these subjects are full of strong opinions but are thin on objective answers.   One person's certainty is another person's skepticism; someone else's common sense just appears as an a prior bias to those who see matters differently.  Sadly,  conversing these controversial subjects can generate more heat than light.   All too often people can get s...

As a regular user of Twitter I've felt the waves of frustration wash over me these past couple of weeks as the service has been hit by one outage after another. This led me to start pondering the problem space [especially as it relates to what I'm currently working on at work] and deduce that the service must have some serious architectural flaws which have nothing to do with the reason usually thrown about by non-technical pundits (i.e. Ruby on Rails is to blame).
