We get questions, asking about the use of the 'orc' moniker, in IRC and at this blog.
When first using IRC, the Freenode 'nickserv' wanted a userid not in current use, and the 'usual suspects I prefer to use were long locked up; so: orc_orc and the related variants I use. The 'Blogger' software added a later constraint to the DNS character set, causing the drop of the Underscore to form a valid domain name.
This pair of latecomers pictured above may be related to one another, but I have to disclaim any connection.
