One thing that I try to do on this site is accompany posts on all topics with links to related materials: both in terms of what I have written and what is out on the wider internet. One way I do this is by leaving comments that link to and quote from relevant news stories and websites. By convention, these comments are attributed to ‘.’ since it doesn’t take long to write and cannot easily be confused with a real person.
Readers who come across relevant stuff that they simply wish to link, rather than say anything about, are encouraged to use the convention as well. If you use ‘email@example.com’ in the box for the email address, your comment will have the ‘Just some news’ gravatar placed beside it.
