On MediaWiki Support Desk, I'm seeing tons of small site users that are having a lot of problems since 1.24 and 1.25 with out of date content.
All this has to do with the fact that the JobRunner is doing so much more, that the default job runner rate, simply isn't really sufficient for those types of sites anymore. Just like other large sites, they really should run it continuously.
I think we should take a hint from phabricator here and advise users to setup this up during install, if the system really has become so dependent on it.
