If anyone is currently experiencing this issue, I would absolutely love to talk to you! I only have a really rudimentary site up right now at http://hallwayapp.com if anyone is even remotely curious (no pun intended).
There's no denying that something gets lost on a Zoom/WebEx/other conference call - attendees are distracted, miscommunications happen, and people have to be assertive to get their message across. This can be overcome by a small team that is 110% driven in their goal, but it's a model that can't be adapted by all industries/sizes/cultures.
I'm still not sure what the solution to this is, but I think there will be a dramatic paradigm shift. Maybe the trigger will be VR or some disruptor we already see coming, but it may be something more approachable.
All of those tools you listed are CRUD-based. I think the space would benefit from something more reactive, where multiple people can "play" on the same screen.
I think part of a solution to that problem is more deliberate communication. Water cooler talk, informal office conversations, whatever you want to call those, while occasionally helpful they can also lead to the creation of information silos between the people participating in these conversations.
The constraint of not having the opportunity to engage in this kind of conversations might actually be beneficial. Distributed teams force you to communicate more efficiently and more purposefully.
It can get a little slow for larger boards – we did multiple weeks of branding iteration in a single board with hundreds of images and sticky notes – but overall I'd highly recommend it.
