i'm never quite sure how important replication is for a DB to succeed. up until recently i didn't need it, and now oracle provides master/master - so that's transparent for me. and i don't have to worry about how to setup the apps to be master/slave aware. who really is using mysql replication. and how interesting was a master/slave setup - the only kind of replication provided up until 4.1 (2004). i would imagine if you know howto setup your apps to work with only one master, you would know about postgres. would really be interested if any middle-sized (not slashdot) websites use mysql replication (which setup) and since when.
