I also have the vague feeling that those tools have hard to understand team permissions, but I'm unclear on how Slite solves this in a better way. Either way, sounds interesting. Congrats on the launch!
The easy way to see that is by checking a Google Drive structure : you have "My Drive", then some folders, some shared, some not, and in parallel "Shared with me" gathering documents that can come from outside your team, and that you can also put in "my drive"... It's centered around individuals and weirdly works for them, but is absolutely not suited to organize and retrieve content as a team.
Slite actually creates a well defined private space for your team, which makes it possible to share by default. When I update our roadmap or our hiring process, I know all the relevant people can see the channel highlighted, and can get updated. In another tool, the authors would have to push a link by email or irc to get their team updated. And this mereley because they knew that else nobody would see it had changed and nobody could retrieve it in a shared folder structure.
Completely side but awesome job on Slate! We have spent a lot of time working on editors, and might switch to it at some point, so keep up the good work!
That makes sense re: teams, thanks!
