If I remember the same incident that you're talking about, it was a single file that had to be manually removed, and the fix was displayed right on the home page of http://archlinux.org for months..
And the fix should come in through the right channel, like the package README or ChangeLog. Not sure if the home page of the whole distribution is the appropriate place for a fix like this.
All that said I'd recommend to anyone new to subscribe to the 'Latest News' RSS feed: http://www.archlinux.org/feeds/news/
