I have a number of different Wordpress blogs on different domains all on the same host, each with their own MySQL database. I'm moving hosts and getting everything setup. I know that since Wordpress 3.0 there's been a Multisite features and I wondered if any of the major bloggers were using it. Anybody got experience with it and know any of the pros or cons? Disk space is cheap though, so I don't have a problem with separate installs. It probably even makes moving individual sites easier since there'd be no messing about with plugin configuration. The other thing I was curious about - assuming I use standalone installs - is whether or not to use separate MySQL databases, or just one database with table prefixes. What do you guys do and why?
