1. Sites can very quickly put up what you might call Queue-Walls in front of their sites. Ocado appears to be using Traffic Defender. "Virtual Waiting Room"

2. It really helps the user if a Queue-Wall gives you an idea of where you are in the queue. Contrast ASDA "you are now in a queue" with Ocado "You are position 28220 of 31978. Your wait time will be more than four hours." Ocado has bad news, but its better than ASDA where you just don't know.

Here are my opinions.

Ethics and conduct

1. Developers should adopt a code of ethics. The ACM has a nice example, if you need one.
2. Be kind, always.
3. Bigotry and intolerance of others is not ever OK.
4. In code, people, everything, seek to understand before judging.
5. It's OK to judge, provided you're also kind.
6. It's hard to create good software. Be respectful.
7. It's easy to criticise and tear down. Don't be an arse.
