Synchronous or Async communication? What's your top choice?

Great question!

I see bubbles as a more casual working tool. I'm not adjusting my lightning and getting my business attire on to record a webinar, but as a part of the workflow enhancing communication.

At the same time, bubbles has a more user-friendly interface and is easier to comment on.

More importantly - it's free. Loom has some similar features in terms of async comms, but it isn't available on the free tier.

When I switched from Loom, I noticed that bubbles doesn't require a rigorous sign up process. You can just add the extension and hit it and go without even entering your email. And when you do want to "sign up", it takes about 5 seconds.
