While I also use -current, I don't think this is good advice to the kinds of people who don't know if they should be running 14.4 or 15.0. There are caveats to running -current (for example, you need to disable the built-in debugging stuff on -current to get decent performance but the debugging stuff is already disabled on actual releases), so I think for new people it's best to recommend they use the latest release (15.0) and they can discover -current when they are more familiar with FreeBSD.
