Hooray! I have been holding out hope for more push-to-talk apps on desktop platforms. It's such a step up from always-on listening. As an audio engineer, I grit my teeth every time there is microphone feedback, echo, or other audio issues on group calls, and these generally don't occur on PTT apps because everyone tends to be muted most of the time. And if it does start happening, the user more easily realizes what they did wrong because they correlate it with the button press. In fact, even if the user does not realize what they did wrong, others on the call can identify the source because "it's only happening when Jane speaks." I can't tell you how many times I've been on a call with feedback where the person who is causing it is complaining about it to the group without realizing it's their own fault and others on the call don't necessarily know, either. This never happens on PTT calls. There's also the obvious privacy benefits, as it avoids the issue where people speak without realizing they are unmuted. PTT is better in nearly every respect. I'm very excited about this. I do have some questions that the website doesn't answer for me: 1. What about screen sharing? Seeing the word "collaboration" implies to me that I should be able to do so, but it's unclear. In the screenshot of the app, I see an icon or two in the right-hand sidebar that might be relevant to this, but they seem kind of generic. 2. What about mobile devices? I routinely do Slack calls where one or two people are on their phone for various reasons. It would be useful to know if that is supported or will be at some point. 3. I want to know more about the encryption. As you're probably aware, there has been a lot of controversy over the security of Zoom. In particular, there is an ongoing lawsuit related to their false claims of end-to-end encryption. [1] I think any new product, especially a chat app, that claims to be end-to-end encrypted really needs to show us the details of its protocol and stack, and ideally open source as many parts of that as possible. Does it use the Signal protocol? The site says "Squawk groups are invite-only and end-to-end encrypted." But which parts are E2E encrypted? The group membership? The message content? The message metadata? Everything? Lastly, it would be great if you could add the app to Homebrew Cask, as it's my preferred way to download and manage apps on macOS. 1: https://gizmodo.com/zoom-accused-of-misrepresenting-security-measures-in-ne-1842756394 https://gizmodo.com/zoom-accused-of-misrepresenting-security...
