For anyone who does not currently use a Code Review tool on their projects, I highly recommend you setup http://codereview.yourdomain.com with Guido's App Engine code review app. It takes seconds to setup and is surprisingly capable.
I'm looking at it, and it seems it makes sense when your team is distributed, but not if the two developers can actually make the code review on the same computer.
Currently, my team is distributed. I am in WA and my partner is located in PA.
However, even when you are sitting right next to each other there is value in a tool like this. If you are reviewing a large change set, you can huddle around the review tool instead of around your normal editor. This way you aren't tempted to make quick changes or fixes to the code on a whim, instead you are annotating the code inline. Code context shortens the length of comments, so you are more willing to make them. In person, I find that a lot of comments are said aloud, but lost forever when you fail to write it down or write it down without any context.
Well, seen this one coming since AppEngine was launched. This should make their Apps offering even more compelling and help steal more marketshare from Microsoft. Seems like a great way for enterprise software startups to get their product in front of customers too.
