> Then people would avoid starting a talk page when the number is 0. This is, in my view, a bad thing.
This is a valid assumption and one we could test. A zero might even
prompt new discussions. We'll never know unless we explore it. I'm
just curious if there are any plans to test this and other similar
hypotheses.
> This number would have to be generated by MediaWiki or Flow, but surely not by MobileFrontEnd. As I said, MobileFrontEnd is only a skin.
Not true. MobileFrontend has a few more bits of code that make it a
little more than a skin - e.g. special pages like Special:Nearby. It
currently records this number via a hook and is agnostic to Flow and
MediaWiki (although this code could easily be added to MediaWiki core
to be standardised)
