Crazy Harry said:Firstly OP its a good call to ask the hard questions - its not the first time this suggestion has crossed our paths and I think it a little unfair that you've scored a hard-ish uncompromising response.
No worries Harry, I'm not taking it personally and the responses are pretty much exactly as what you see on other older forums when an upgrade is suggested... but they're quickly forgotten when the upgrade happens and once they've had a chance to get used to it (if moving to a good platform like Discourse anyway, which was created by the same people behind Stack Overflow).
I do think it's a little sad that the resistance will probably result in the admin deciding not to upgrade, because users will be missing out on so much. Even simple things like the ability to like a post as a quick acknowledgment or thank you for someone replying to your thread would make a big difference, and @tomscott and I have mentioned quite a few other benefits.
Overall I think an old platform hurts user-retention as more modern platforms are just easier (and more enjoyable/less frustrating) to use - so while the old-hats will happily plod on... fewer and fewer newer members will become regulars in the same way.
It all boils down to what the admin and the community wants - do you want more people to join and stay? If so a more modern platform will almost certainly help. (Discourse is free/open-source btw, and if the admin here needs help with the switch over I'd be happy to help)
