I understand that this is a fairly open-ended question, but I just wanted to see what the community thinks are very well done. An example of what I think is a well designed website is Rands In Repose (http://randsinrepose.com/) due to its clean layout and readability.
EDIT: Just to be clear, any personal website is up for discussion, but if they had a software development or entrepreneurial lean, that would be even better.
