My do-all-the-thing-I-put-off project for the forum app is really coming together. I may still pull in a few things, but right now I'm reimagining the PM bits to be more chat-like instead of resembling email. It's the thing that I'm least interested in doing, but it's long overdue. It isn't technically difficult, I'm just not that into it. I think the one other thing I may bring in is the "update Q&A forum page in real-time" story.
I've been periodically updating CoasterBuzz with new builds, and the thing that makes me happy is that I notice the forum less. That is to say, it doesn't get in the way, there's just the conversation. The two biggest wins are the revised post quoting, and more importantly, the ability to upload images into the post. The latter has been a requested feature for well over a decade, and often the reason that people don't use the open source project, and probably pass on the hosted version. You could always embed images hosted elsewhere, but that's a crappy experience.
I got some validation from a guy who is using it and integrating it with some other stuff, and he's even using Azure AD to authenticate users, something I wasn't even sure could work. I have a generic OAuth provider there, but never really tried it. It would be a big deal to the corporate world if I set up an OAuth-only private option, and I know how I would do it, but I'm going to save that for the next version. I certainly don't need it, but I can see how others would value it.
With the image uploading, maybe it's time to market it a little on the hosted side. Lacking that feature, I was never comfortable to throw any money at selling it, but like I said, now I "see the forum" less. That brings me joy.
