Blog Surfing Etiquette

All this blogging and reading and commenting on other blogs has brought up a question about etiquette. Most comment sections identify the commenter by name only (whatever they’ve signed in as). My instinct (as Karen Syed has trained me now) is to always include a link to one of my sites after my name or some kind of reference, such as: Author of The Sex Club. If someone likes what I’ve said and wants to know more about me, my blog, or my novel, it seems logical to let them know where to find me.

But I wonder: Is this socially acceptable in the blogosphere? A random survey of the blogs I visit indicates that most posters do not even include a full name signature, they just let the comment box identify them. So it uncool to post a url? Does it depend on the blog site and how well you know the person? What is your practice? What is your opinion?
