@adamprocter I've had similar thoughts about the support channels thing but when I actually sit down and work through which ones I'd remove, things quickly stall out.
For example, it seems a bit silly if you can't contact Manton on MB so I don't think removing that's a goer. E-mail seems essential for private communication. GitHub has the least mainstream appeal but it's where developers are, it exposes discussions publicly and has pretty good tools for notifications, conversation status, indicating support, etc.
So that leaves… Slack? I'd personally drop it but I can understand that when you're like Manton and starting from a standing start, you want to foster community in any way that you can.
This exercise always brings me back to the same conclusion: it's not so much that Manton is managing support incorrectly, it's that he needs a bigger development team. That's easy to say from my arm chair and it's (I'd guess) something that's impossible given MB's current revenue but it really seems like he's taken on a truly Herculean task.
Again, easy for me to say but I do wonder if the main service shouldn't be open sourced. I think people would still pay (given the convenience) and it would at least let those of us who might be able to help contribute more.
