anonymity = notoreity?
Not necessarily in blogging, but in literature:
[Sir Walter] Scott's case illustrates a paradox that we find over and over again: the anonymous writer who does not truly attempt to remain unknown. For the most part, he enjoyed the speculation his anonymity attracted. "I have seldom felt more satisfaction than when, returning from a pleasure voyage, I found Waverley in the zenith of popularity, and public curiosity in full cry after the name of the author". English (and Scottish) literature is full of similar cases - of authors who went to great lengths to maintain anonymity, but thereby promoted their readers' interest in the authorship of a work. The main lesson is a simple one: that anonymity is most successful when it provokes the search for an author.
