There was a recent discussion going on if Fedora 20 should drop rsyslog and just using systemd journal. A lot of people are afraid of systemd and its journal, this a pity.
Well, there are pros and cons about this kind of logging. For System administrators daily use, journalctl is a powerful tool simplifying the hunt for log file entries.
On the other hand, there are AFAIK no monitoring tools (yet) that can work with journalctl. Those first need to be developed. A Nagios plug-in should be implemented quite quickly.
