I need to talk to someone face to face, online.  

Both my kid's colleges went online and both have adopted Zoom as the application of choice for lectures and professor office hours.

We've been using join.me for years for conferences and screen-sharing. It's really well-suited for the latter because of its built-in markup tools: highlighter, pen, pointer are all useful when you're making visual connections with your team. Haven't used it as much for face-to-face contact. But we tend to look at things together more often than we need to look at each other. It's good for online presentations, too.

That chat I talked about in my topic happened on Zoom. But we use Slack a lot at work, and it's pretty amazing. Really quick and easy to get a call going. Great screensharing and mark-up tools. We've been using it even more now that we're all stuck working from home. And it makes it easier. Feels like your friends and coworkers are still around and you can stay connected. 

We use Zoom for my son's school (nothing cuter than a whole bunch of 5 year olds on a video call!). For family, you can now do group Facetime calls. You just click on video chat from a group text message.

Dropbox just announced you can now "save transcripts and video from your Zoom Meetings directly to Dropbox, and help everyone stay up to date, even if they can’t attend live."

That sounds like a pretty useful addition for distributed teams working from home, no?

I notice that Zoom now has some great screen markup tools. Better than join.me's. And they work with the free version, not just the paid one.  Zoom got 600,000 new users in a single day in March, so they are probably pretty stressed right now. But it'll settle down and seems to be becoming the standard. Great system.
