I've been running websites and forums since 1997. I've seen it all and been through 1000s of software, addons, scripts from Matt's Script archive, mm_ImageSwaps and all the rest along the way fighting ie5 vs mozilla.
Most of the 100+ voted features that have been around for a decade are
- bloat that most customers don't need from a forum software (eg, blogs, groups, store, cms, etc that isn't really a core forum product)
- technically limited / not wide spread adoption (eg, webp support and similar odd-support for modern images/vid/etc)
- obsolete (amp, etc)
The only items on the first page that I agree with and would use (sorting by most votes) are the integration items. SSO, and so forth.
Still, none of that is what I want in 2.3.
I want jquery removed. I want a react or nextJS interface. I want a modern, portable, mobile-first app that's light-weight and competes with WP in search engines due to code-to-content ratios.
I want the ability to have users install or configure an app or something to allow direct camera share like facebook, snapchat, google, etc do all from my phone's camera context menu. We are losing because people share elsewhere first because it's easier.
phone - click pic - share icon - post it
everywhere else
for us,
its
phone - click pic -close camera app - open browser - type in url - nav to a forum - click new thread - click attach - browse and try to find the pic you just took ....
the answer is so blatantly obvious why we are losing.
We are in a media-first, mobile first world, and XF is not there yet.
I don't know how we do it. I don't know how we get into the phone's native share without an app for every site.
But then i think about xf cloud, and perhaps that's the first step into become a managed service where there's an XF hosted solution, 1 app, and you can still do whatever you want with your theme, addons, etc
i don't know. i'm not building 2.3

But this is what I need.
If i don't get this soon, my site will be closed soon. Traffic has dropped from 20k a day to 20k a month over the years, and yet, all my 'old friends' are posting their stuff on facebook constantly while my site gets ignored. All because it's easier to do it and people are lazy.
Once you take the human use case into perspective, it's easy to see why xf and forums in general are not relevant competitors.
