Excerpts from Platonides's message of Sun Aug 01 17:39:19 -0400 2010:
I'm not sure that's comparable. If WordPress complains for being an old version, unsavy users will want it to be upgraded for them. Whereas if they watched the relevant mailing list they probably have the required skills to manually update. (Since they chose a 'managed' mediawiki, it's not that they would be required to do it anyway)
Right, so it's an interesting combination of factors.
* Does the application tell the user that their version is out of date? * Does the application let an unsavvy user upgrade the application with a single click?
Our experience suggests that if the answers to these questions are yes, unsavvy users will definitely exercise the feature.
Does that mean that they chose that version despite being outdated? I wonder if all those 1.5.8 installs are due to thinking 1.5 is greater than 1.15
No, that just means they installed 1.5.8 back when it was still the default, and then we didn't manage to upgrade them.
There's probably some interesting knowledge on looking how they patched it, but I don't know how to easily extract it.
A good starting point would probablyb e "most edited files".
