I would like to suggest that AO provide a RDF (and possible XML) news feed that can be used by (amongst many, many others) Ximian Evolutions newsfeed.
I think this is the same format that 'news tickers' use but I have no experience of them.
I would suggest using slashdot as an example, including their rules for only allowing one connection every 30 minutes.
http://slashdot.org/code.shtml (Second heading down on the page)
I'm not sure (being a newbie) if I should be posting a poll for this, but if others think this is a good idea they can do it.
Thank you for your time.
