I am a member of this list for a long time, but never asked a question nor answered one yet, just a read-only mode follower :)
I filter the feeds by the sender since there are lots of messages going around. I may advice two efficient ways of following this list –
1. digest mode membership : http://www.freelists.org/webpage/oracle-l
2. following over an rss reader : http://www.freelists.org/archives/oracle-l/feed.rss
At most I can read maybe %10 of the content daily, but still it is still very beneficial, there are really hidden rdbms and os experts out there, believe me.
