I guess anyone who wants to comment (but we are talking to each other, or talking to ourself perhaps, as two independent outcroppings of the "UR-Peter"?) could check out:

...both of which have forum sections for various authors - including authors who have websites of their own. They're a way to both discuss the authors' work and, if the author obliges, to actually converse with the author. Authors also sometimes post news about themselves, which might also go out on their own email lists and blogs/LJs, but it's a centralised place for such stuff I guess.
I don't
think that there's any real competition between authors as far as how much attention they get goes and so on...
There needn't be a limit to how many authors are included either... And I think if we did it, it'd be great if we had a note saying "Any Australian author who wishes to be included in this forum need only contact us... Likewise any fan who feels an Australian author warrants discussion can suggest them too." Unless we want it strictly authorised only - not 100% sure with the two fora above how it's done.
