Just received a mail from Geert De Paep, the guy behind dba-village, that he as well has started a blog: http://geertdepaep.wordpress.com.
As Geert is a collegue and friend, I know he has a very profound knowledge of oracle in general and high-availability in particular, so his blog is a real must read.
His first article is one about the use of oracle streams to migrate and upgrade databases.
